I guess your nerves get friggled up with guys like me asking the "obvious" for the 20th time, huh?
Not at all. I enjoy answering questions here because I will almost always learn something in the process, and I enjoy learning. A nice by-product of this is that I get to help someone else in the process of learning new things myself.

I just see no point in re-typing an answer to a question that has already been thoroughly covered in another thread.

If someone has taken the time to read information in a thread I linked to, the data sheet, manual, etc, and they still have a question about some part of it they aren't 100% clear on, then I'm more than happy to attempt to elaborate.
