A posting from a new user in the forums, reminded me that it isn't initially clear to newer people just how useful the forums can be. I can remember visiting the forums, feeling confused by all the headings, alarmed by how aggressive some people seemed to be, and then unsure how helpful they could be to me, when I first started in SL.
The SL forums are currently the best place to find official announcements about down time or updates, a good place to find information about new products or events, and a brilliant place to ask a question about SL. Even if you only "lurk" and don't post, they can be very useful indeed.
One of the most useful automated searches is hidden in the bar across the top: "new posts". Clicking on this will throw up a list of new posts since you last visited the forums, newest first, and enable you to see what the current hot topics are, and scroll down the list to find anything of interest.
