One of the best ways to get help with questions about your Mac is to subscribe to appropriate Mailing Lists. Most are moderated and therefore are kept focused and the membership is kept private.

One of the best sources of well moderated and valuable Mac lists is Low End Mac. There are lists for topics ranging from general discussion to Vintage Macs to iMacs. A new source is MacLaunch which where Low End Mac has moved all it's lists to.

Another source of mailing lists is Topica. Topica is a list server and they have an evergrowing number of lists on most topics. A couple of the Mac lists I subscribe to have moved there. They have 20 or so Mac specific lists and the site is searchable.
