So, what if you did happen to have a question about something posted there?
Good point, I'll moderate and post any discussions and questions that are of general interest.
And thanks for explaining the addition of the captchas (which don't work anyway, as you may have noticed).
They work 97% of the time. Most of the stuff that gets through is by real humans who sit and register and post. It's a horrible job.
Does the rest of the site allowing posting without having an account?
No. In fact, I often ponder a way to make registration HARDER because it's a fairly low barrier these days. You might have some idea of the daily scourge of spammers we face, but if not, there are a LOT of attempts to post junk here.
