I've installed Mollom. This does textual analysis of comments, hits you with a captcha if it thinks it's spam.
I'm hoping it'll be more effective/less annoying than the current captcha, we'll see.
More importantly, once you've posted more than 5 comments, it's automatically disabled - so regular users won't get captchas any more. We might need to up that threshold if we still get a lot of spam come through.

Hi, it's glitching for me. I tried to edit a post I wrote earlier today and was forbidden to proceed until I filled out the "captcha" (I'm assuming that's the thing with the letters you have to copy?) -- the problem was although there was a prompt instruction me to do this, there was NO captcha to be seen! So I could not fill in the letters as there were none! So I just pressed the "save" button again to post and then it said that my comment was detected as spam and would not be allowed to be posted! I tried again it happened the same way.
So I gave up on editting that comment and decided to post my edits in a new comment (not the entire comment again, just the thing I wanted to add) -- and again it said I was detected as spam and being blocked! I was able to post on another thread without trouble, but it seems for that particular thread I have been blocked from further comments?
It really sucked... I never had the old system cause any problems.
Also, I have about two-dozen posts... you said after 5 posts people aren't bothered with this captcha anymore... so I don't know why this is occuring.
I realize this is complicated technical stuff so I hope you don't interpret this as me berrating you... I'm frustrated but put no blame on you for the problem. I hope it can be fixed soon, though!
