But, at the risk of a bit too much pop psychology, does the fact you felt the need to post annonymously hint at ethical reservations on your part? (If so, perhaps these answers will help allay or even resolve them.)

However, if the embarrassment you felt is merely at some sense of ignorance then I see no need for it. What's the most used area here? SOPW. We share our ignorance in the OPs there... to our mutual benefit.

...and good luck, in any case, on the challenge!
