Viable alternatives for serious aviation discussion

Once again I will post below for anyone interested in serious aviation
related discussion the following alternative web based newsgroups. I
will repost this notice periodically.
Many of the pilots who used to post here are now posting at the
following forums. It's a slightly different format from Usenet but in
lieu of what's happening on RAP, you just might want to take a look at
these alternatives.

Reading the answers that follow this post might help to serve as an
added incentive for you to give these groups a try. :-))
