The TeX Stackexchange is a good place to ask questions about LaTeX. (As an example, this question is similar to the problem solved here.)

One of the many threads on TeX Stackexchange that I memorized while tackling the problem. Your point is well taken, however, I have never once treated forums like that as if they grant write access. I seek out solutions that are already there but don't bother trying to have people solve mine. Perhaps because most technical problems of this nature don't end up being nearly so intractable.
