An alias is a string of characters that can be put in the place of the string starting your original e-mail address. The IS address containing an alias has the form of brandejs@mail.ambis.cz. Aliases may only consist of letters (of any case) and digits (must not start with these, though). Furthermore, they must be free of diacritics. The minimum length of an alias is three characters.
If an alias is found to be violating some basic principles of decency, it might be made non-functional by IS administrators. Users are not allowed to use aliases intended to make others believe they are someone else either.

Logically, it is only the alias no other IS user is using that can be selected. Please create the one that other people will be able to associate you with easily.

To create a new alias (or change the old one), enter it (or the old one) into the text field and click on 'Save user name'.
