I confirmed the captcha issue, and verified I fixed it this time. I've also gone ahead and lowered the threshold for verification/moderation from 3 posts to 1. The intention of the verification/captcha check was never to be a test of will to see if you're patient enough to stick around, just a way to stop spam, as we've historically have had large issues with it. Bots would slam the registration page until they finally pass it and then they'd just spam, at least with first post moderation we can remove spam posts and spambots before their posts are even visible. If we've approved your first post, the likelihood of you being a bot is extremely low (and if you are that's a LOT of work just to spam a Touhou forum), so I went ahead and lowered it to 1.
This includes PM rights as well, after your first post you should not have to perform any captchas or clear post moderation before you can PM or post. If you're still getting captcha'ed and you have at least 1 post let me know and I'll work on it. I've verified on my test account with 2 posts I can post/pm.
Sorry about that and thanks for reporting the issue to me!
