Along similar lines (site glitches) ...if it seems like something doesn't post due to an error message, before trying repeatedly to post again- copy your post just in case so you don't have to retype everything if it's not there, but refresh the thread just to check- every time I've gotten this error message the post is there. I don't know why people get this message when their post did successfully go through, but I see multiple threads where people have posted up to 5 or 6 times and I assume it's due to getting error messages like this.
