Registration and Log In

There are two general types of users in the Web-SynDic system: a regular user and a registered user. A regular user is any Web-SynDic user and she/he is not required to register and log in the web system. A registered user has to have an account in the web system, and his/her personal information including limits for solving and generating ANLDE systems is saved in personal user profile.

Web-SynDic allows any regular user to register whenever she/he wishes. When the registration is complete, this user may log in the web system (using assigned unique identifier: nickname and password), afterward some additional Web-SynDic features may be used. Web-SynDic allows a registered user to edit and store personal profile with user limits independently on session lifetime.

The registration is initialized with the Register button in the Log In form. Afterward the web system returns the form, shown in Fig. 19. The user feeds the fields of the form with information he/she wishes to provide about himself/herself , and clicks on the Register button to complete registration. The required fields for filling are marked with ''*'' sign. A nickname may contain only Latin letters, numbers and underscores; also a nickname contains at least 2 and no more than 32 characters. A password may contain at least 4 and no more than 32 characters. If there is an error in filled fields, then Web-SynDic responds with a corresponding error message; it includes a reason of the error.

When the registration has been completed, the user may log in the Web-SynDic system. To do this, he/she enters login and password in the Log In form and clicks on the Log in button.

After successful login, contents of main window are changed. Log In area now contains user status in the Web-SynDic system. User Profile link appears in User Menu to provide additional Web-SynDic feature.

Logout from the web system is performed using Log out link. It appears after successful login in Log In area. It is strongly recommended for every registered user to explicitly log out at the end of her/his session.
