First, minor point - the link to the Character Submission Guidelines is no longer valid, as those guidelines have been replaced. It should be replaced with a link to [noparse]http://forums.layonara.com/character-submissions/225662-character-submission-approvals-policies-new-players-start-here.html[/noparse].
Now, the other issue (the one I've been meaning to mention for some time), is that of the class choice fields. I think that all Prestige classes save Weaponmaster, Duelist, Undead Hunter and Battlerager (those that can be approved on submission) should be removed from the option list, to spare new applicants confusion.
Several times we've heard the complaint "but if you can't be approved for them, why are they on the list?" While I think that new applicants ought to read the rules, it does make things more confusing than they need to be.
Anyway, my suggestions for improving the tool, long overdue.
