as soon as you delete a user from a board all messages of the user are displayed as messages of the guest user. however in the database the username of the original user is still stored. in the forum table, in the topic table and in the message table
it would be really cool to display the real username of the deleted user (not linked in any way) instead of the guest user. especially when you have a few users deleted it gets quite confusing who the original author was.
that would help a lot in my yaf project ...
