Dang, you shouldn't do that. I leave mine on alot, but by then the ram can olny hold/delete so much and it keeps wearing away. It eventually runs like trash and luckily you can just turn it off and the ram wipes and is just like new. I keep my computer on still, I don't pay the bills
As for me and PHPBB, we go back together. I've been using it a lot for my other forum, it's the best board out there, without a doubt.
