has been said before, and im gonna say it again: enabling HTML is DANGEROUS, if u dont know what you're doing, then dont do it!
YaBB/BB codes are as easy as HTML to use, tho limited, its secure
now, if u still dont care, and still want to do this, u can open profile.php and remove these 4 lines of codes
$signature = str_replace("<","<",$signature);
$signature = str_replace(">",">",$signature);
$member['signature'] = str_replace("<","<",$member['signature']);
$member['signature'] = str_replace(">",">",$member['signature']);
hasnt been tested, so if its not working dont blame me
and if someone does something nasty on your forum, dont blame us or yabb software
btw... those 4 lines could be replaced with htmlspecialchars() so quote sign wont cause trouble too
