It could be possible, to say something like
Code:
if(usergroup == "Registered user" && post > 50)
move user to usergroup "accepted user"
And then have some restrictions to say
Code:
if(usergroup == "Registered user")
hide signature
And just have the "accepted user" group with the exact same restrictions as the "registered user".
I know it would be alot of checking on userprofiles, but it would give us some potential in user management...
//edit
hmm... the AJAX "quick-reply" and "edit" feature seems borked in FF 1.0.5...
For a quick-reply it gives you the "posting reply" and then stops without reloading the page, so you dont know if your reply has been accepted, and with the "edit" you have to press it twice, yet that will direct you to the "Advanced editing" instead of the "in-thread" editing...
