Great
I installed it and....

When I wrote any number in ban timer is always display that is pernament ban
Reason of ban doesn't see in PM, but in code, in changeuser.php are lines:

$banreason = $html -> do_markup($banreason);
$banreason =nl2br($banreason);
$banreason = eregi_replace("{$config['images']}", "{$config['imageurl']}" , $banreason);

What is mean "nl2br" in code

I feel that is sth wrong
