@qwerty Are you freakin' serious or punking us? If basics such as this are beyond you then you have absolutely no business deploying server based anything on the Internet. Much less a juicy target for crackers like a forum. Seriously irresponsible. Your name/reputation will be crap once your site is cracked and your users forever hate you. If this sounds harsh, it is because it is meant to. Moderator was being polite.
