This is a collection of, you guessed it, frequently asked questions.

If you have a question, then ask it on the mailing list (of course, you would ask Google, and also search this site and on the mailing list archives before actually posting a question, lest you look silly by asking something that can be easily found in the archives).

If the answer to your question asked on the mailing list contains new information, it should make its way here (or to the Information or HowTo areas). It is *your* duty to assist in this process - if your question is answered to your satisfaction, then the onus is on *you* to update the wiki as "payment" for having your question answered.
