When you edit your own posts, you should now see your post header and signature seperated out from your post. This should help with some of the confusion we've been having with the table tags.
Remember, if you open a table in your header, close it in your sig. If you remove a table tag from your header, make sure you take the close table tag out of your sig.
Always match the total # of table and /table tags in your posts!
//edit: Down to one last glitch - I screwed up something in the newthread.php I think - I need to check it. When you edit the first post in a thread it adds extra spaces in. This doesn't happen in any post except the first one in a thread.
