Captcha, as most will know, is the code thing that you type in to various sites to try and stop automated form submission - going some way to limiting spam and brute force attempts to access accounts. We have it enabled for everything except posting and searching. Searching can stay without it - hammering away on our search won't crash he site like the bad old days. However posting..... Would stop almost all of the bulk spam, but would be a minor pain in a functions that people use daily. Vote please - would you prefer to fill in a captcha code when you post, or suffer some irritating spammer?
