If SuperMemo asks you for a password or there is a red registration bar below the navigation bar, you are using a locked copy of SuperMemo. To unlock SuperMemo, input the password received in response to your order with File : Registration : Input password (Ctrl+Shift+I) or run the registration procedure as described below.

Important! We are sending you the password and further instructions within a business day. If you do not hear from us in two days, please write to SuperMemoMail. The most likely reason ... you have misspelled your e-mail address when ordering

This is how the red registration bar looks like:

When you use locked SuperMemo, you are given a credit of 100 points. Once this credit is used up, you will be asked to input the registration password. The credit available is displayed in the parentheses on the red registration bar (see above).

You can register SuperMemo at SuperMemo World and become a registered user of SuperMemo:

1. Click the red registration bar to open the registration dialog box (you can also open this dialog box if you (1) choose Register when SuperMemo asks you for the password or (2) choose File : Registration : Request password)
2. Fill out the fields Name, Country and Phone
3. Click Register
4. Respond with Yes to Send e-mail now?

Those four steps will result in sending an e-mail to register(AT)supermemo(.)com with your registration data. In response you will receive further instructions (how to pay for SuperMemo, how to get the registration password and how to input the password).

Important! If you have already purchased SuperMemo, you do not have to register it! You have been registered at the moment of charging your credit card. The only thing you have to do is to unlock SuperMemo by providing the password with File : Registration : Input password (Ctrl+Shift+I). Your password will be sent in response to your order within a business day. You are unlikely to ever need to input your password twice. However, in case you ever lost it, write to SuperMemoMail

You may wonder what is the reason behind using this complex registration mechanism. The advantage is ....

You can freely spread bare SuperMemo among your colleagues without violating your user license!

Important! You can only redistribute the following three files from the SuperMemo folder:

• sm99.exe (SuperMemo 99)
• \bin\tips.txt (the file with questions for Question of the Day)
• \bin\smhelp.chm (help file with the compiled SuperMemo Website)

In particular you must not redistribute your collections along with SuperMemo! Collections keep your registration data. Spreading them along with SuperMemo will violate your user license

If you want to redistribute your own collections, you must use File : Registration : Unregister before putting your collections on the web or passing them to your colleagues. Please write to library(AT)super-memory(.)com if you have questions about redistributing your collections with SuperMemo

Our apology

We apologize for the inconvenience related to the registration process!

The goal of SuperMemo World is to popularize SuperMemo. We are happy with every new member of the SuperMemo family. We wanted to provide our customers with a free working version of SuperMemo. At the same time, we could not forget that the company has to earn for its operations. On one hand we cannot make all SuperMemos free or shareware, on the other, we cannot reward 'clever' users with an easy way to circumvent the license fee as we do not want to contribute to the world where living by your wits pays by hook or by crook

Our experience showed that the shareware approach does not work at all (which refers only to our DOS and Windows versions)! 
In the years 1991-1999 we have gained thousands of users of SuperMemo 2, SuperMemo 5, SuperMemo 6 and SuperMemo 7 (all these versions of SuperMemo have been ultimately released as freeware). At the same time, we received less than 10 shareware contributions while the number of support requests was nearly a thousand times greater!

In 1998, we opted for the current registration scheme and we have not received a single complaint until now

Frequently Asked Questions

(Michael Duggan, Canada, Oct 7, 1998)
Question:
I am having difficulty unlocking SuperMemo? I get a dialogue box that asks whether I want to send e-mail now. I click Yes. But instead of sending my information to register I receive an error message "Cannot send e-mail - user abort". How do I register?
Answer:

1. All users who order SuperMemo are registered automatically
2. The error message may result from problems in communication between SuperMemo and your e-mail software. If you respond with No to Send e-mail now?, SuperMemo will generate a text file that you can e-mail to register(AT)supermemo(.)com

Question:
I read that I am automatically registered upon my credit card purchase; however, I didn't get a password to remove the red stripe and hopefully display other program options I read about. I tried my order number which didn't work. Please email me some guidance. I can't wait to get started in using your program.
Answer:

1. You are automatically registered in our customer database and you can start using the program immediately
2. Within a business day you will receive further instructions that will help you remove the red stripe
3. You do not need the password to use 'other program options'. It is enough you turn on the professional mode with File : Level : Professional

(T. N., Austria, Nov 16, 1998)
Question:
You have sent me an e-mail with the password to unlock SuperMemo, but where do I have to fill it in? When I click the red bar, SuperMemo asks me to send e-mail to register(AT)supermemo(.)com
Answer:
Your instructions should indicate that you can use File : Registration : Input password (Ctrl+Shift+I) to provide the password. You do not have to register your copy at SuperMemo World. This is done automatically at placing the order
