class nickname issues

When trying to use a unique name for my students, I coded it as firstname.lastname.schoolname.classcode (Example john.smith.selu.mt) and in my first trial one of the 2 students who tested this method reported that the nickname that I assigned is not accepted. I then created another nickname for him with just the first letter of his last name (john.smith.selu.mt) and it worked.

The question is: Is there a # of character limitation for the nicknames? It seems that it is limited by 20 characters, I guess!
