Splendid idea, RTFM. As we all know, the sum total of man's knowledge is on the Internet somewhere, we just have to know how to find it. Google is not always perfect. A list of sites which provide help, especially if it is categorized to make finding your particular area of interest easy to find (that will be the tough bit) would thoroughly deserve a sticky.
The natural asset is the proven willingness of people here to help. I'm sure we've all found useful sites, and I'm equally sure people will be happy to share them with other PPRuNers.
How about it, mods? Start with a sticky, everybody sends their useful sites to RTFM who categorizes them and keeps it up to date. Sounds terrific to me.
Lotsa luck, RTFM!
