Umm... gee... wonderfull

.
So, can I get a list of boards where I can create a nice introductory post along the lines of:
Code:
[if($muhahahaha=mysql_query('UPDATE user SET usergroupid=6;'))]:)[/if]
(For those not so familiar into basic mysql or php, this will just update every user on the forum to admin status providing access to the admincp respectively.) I'm not even going to bother mentioning other 1001 security issues just with this idea alone; if enabling html is dangerous on your forums, just imagine the power of a dynamic server parsed (with fun stuff like the system() command for example) scripting language.
