It certainly sounds as if you're doing a lot of good, Gus. Feel free to post any questions that may be relevant to your purpose in PP. You'll see serious questions there, and not so serious questions. Practical and not so practical. But that shouldn't put off anyone with different kinds of questions to ask. Any answers you might like to post would, of course, also be welcome. And do not at all feel shy of posting combination questions/answers! If you know something lots of other people don't, by no means should you fail to post in the question/answer mode!

It's just another modern, web, information-transfer site. That's all! Take care.
