Second-level domain name and documentation update

Hi there everybody. Time for some news.

1. We finally have a second-level domain name: I took too much time to think about that (the most obvious ones already belong to somebody else :-D), then I decided to go the easy way :-D.Now, you can use virtualboxes.org and virtualbox.wordpress.com indifferently, you’ll get there. You do not need to update your existing links, but we encourage you to use virtualboxes.org in new ones, as we find it easy to remember (and that’s a good use for 15$ :-)).
2. We also have a new theme: since our posts are brief, that’s the right site to give P2 a chance. We also plan to enable comments (they are very fast and easy to use in P2) and use them as replacement for the (dying) forums.
3. Our documentation has never been plentiful; maybe it will never become as so, but I will (slowly) try to catch the most common questions I know you’ve asked in several mailing lists (we’ve never acknowledged the support you give to us, so it’s time: thanks!) and add them. First comes a little guide to manage username and passwords in GNU/Linux, Free/Net/OpenBSD and other UN*X and UN*X-like virtual machines.
