At the urging of one our esteemed members, I've changed the way the anti-bot code works. The member, who shall remain nameless, wrote me and said:
"Every once in a while I will enter a post (usually a long one, naturally) and then mistype the verification word. When I hit the back button my post has dissapeared and my mood has shifted from serene benevolence to verging on the psychotic."
I understand, and it made me awfully cranky too. It worked this way because I couldn't find the &^$@! code to return folks to the Preview screen in the case of a mis-typed anti-bot code. I've fixed this now so that if this happens you don't lose your post, instead you get gracefully returned to the post/preview screen with a [span style="background-color: rgb(255, 255, 0); font-weight: bold;"]glaring message[/span] at the top, and your message is still there. If you have any problems with the way this works (or if it doesn't work for you) please let me know.
