Too many spammers are getting around the ReCaptcha security in member registrations, so I think it's time to change things around a little...
One of the most successful methods of human verification is an easy Question and Answer. The answer shouldn't be one that is easily Googled (by easily I mean by bots, not humans) and preferably unique to this site, so for example :-
Q) Which in the following list is NOT part of a Pedal Steel Guitar? Leg|String|Lever|Screen|Neck
Was one I came up with quickly just to get it implemented. But as I don't know much about the subject, feel free to reply here with your own suggestion(s). The more questions there are, the better.
Don't make it too hard - genuine potential members, i.e. anyone with even a passing interest in Steel Guitar, should be able to answer it correctly.
Also, questions can have more than one correct answer, if need be.
One quick point - I'll remove any Q&As from this thread when (if) I use them in the actual registration process, as leaving them visible here would be counter-productive - a list of all the questions and their answers would be a bit silly to leave up, after all!
