A few things that would be nice to have as part of the user profile:

1. what to call you?

2. One picture that shows what the student actually looks like (for security and enhanced ability to interact), and another to use for individual expression in forum posts

3. a really simple request to have a site administrator change e-mail address for a student

reasoning for 1 - having a role sheet for official grades with one name set and another role sheet with nicknames can be a pain to resolve at times

reasoning for 2 - would really like to know what the students look like, but do not want to infringe on individual expression

reasoning for 3 - students need the ability to change an email address, but disgruntled students enter invalid addresses which lead to already-expressed problems with undeliverable forum or message posts.
