Yeah, I have been getting that all day ~ when you get that hit your little back arrow at the top of your page and then try to resubmit. It has worked for me everytime. It tells me that I have already posted that, but it shows up in the forum that way...
Once again, this is an issue with the server that Ken is working on. He really has his hands full and is trying to deal with everything at once. He will get everything back up and running like clockwork soon :sunny:
