If you want to put out cash for a better server, go for it
I think all the main boards should be invitation only... But that would cause problems...When the traffic gets this bad, it might be a good idea to close the forum to the visitors and the 0 posters.
Was just about to post that I noticed that the online user list and "users viewing this topic" areas are gone. The site is running smooth as silk here.The board should be much faster now. I've disabled a few settings and have temporarily disallowed guests from browsing the board.
