Sorry about that. I have investigated the code and I think the combination of using a customized verification module and my manual edits to require a "1" at the end cause multiple problems. I have made some changes to the code, and I think I have fixed it all now. Note that when you want to send a private message, the prompt now tells you to add a "1" to the end of the code (to help further deter bots that *can* read captcha images, which I was having problems with too, I think). That wasn't the only problem, but I have made it part of the solution. Unfortunately I don't have the energy to add that bit to the message for all languages, so anybody who uses the forums in another language won't be informed/reminded to add the "1" to the end of the captcha code. Hopefully we'll help them figure it out one way or another, or everybody uses English. Thanks for bringing it to my attention.
