1) We have user groups. Administrators, Registered Users, Moderators, etc. Could you explain what you mean, a bit more?
2) Use basic HTML. < br > without the spaces will give you a new line, < I > without the spaces will give you italics, but remember to close the tag with a </ I >. Replace the I with a B for bold, or a U for underlined, or an S for a strikethrough.
You have to register your ezboard name, and after that I can merge these two accounts. Then your post count will be restored, for the most part.
And apparantly only Admins can add HTML to a user title. But that doesn't seem to work, as Grevious put line breaks in his... Another thing to look up later.
