Formatting problems have been fixed. All you have to do is clear your browser's cache (cookies, temp files, etc) and everything will be restored to normal.
Regarding the delay in posting/pm's - it's a necessary evil. We have a massively powerful dedicated server. You can tell from how quickly a page loads up. Now the delay shows you the amount of security features each bit of new data (post) has to go through to be written to the database (posted).
That is because we have had multiple very heavy, very sophisticated hacking attempts on the site in the last month. While the security features held, I am not taking any chances. So every bit of new data that gets written, goes through a ton of security screenings before it makes it into the database/goes public. Can you imagine the delay if the server wasn't as powerful as it is?
