...and another thing: no way am I taking any kind of test. At a certain point in my life I swore that I would never again take any kind of exam. I have kept that oath so far. Also, I can think of nothing worse than having a spirit of competition invading this site. A monthly test? Give me strength...
What to do about the tattoo requests? Accept that the system may not deliver perfect results every time. Many versions of varying quality may be proposed, but we always seem to be able to correct the mistakes, and offer something which works grammatically. What the OP then does, who knows? You can lead a horse to water...
Cinefactus says he has no interest in tattoos, but I hope he doesn't underestimate their importance in providing a continuous flow of interesting problems, whose solution may not always (alas) interest the OP, but which stimulate the very discussion, the thinking-out, the to-and-fro debate which I believe he does value. That, to me, is the 'payment' that we get for this free service.
(Homework-dodgers are a slightly different case. I think you're a bit rough on them, but I understand why. Some bland formula like: 'we are not convinced this is your own work, and so are unable to help you at this time' would probably be better than the telling-off, but maybe that's just me being English.)
PS I looked at that thread from IBBO about Never retreat... Poor guy, never really got it. It's frustrating, but I still don't think it's really his fault. Just ignorant and inexperienced; he was, at least, always polite.
