Spits-vs-109's and Zekes-vs-Wildcats are both Warbirds of Prey servers. They are full-switch, have their own forums and maintain stats for the pilots that fly there. They also host a TeamSpeak server. Here's their link:

Guts-n-Glory is a great server hosted by RaVen that is VERY well done. It's been expanded a bit to include content other than just WWI.
WoW (Winds of War) is hosted by the FA squad and is an excellent server as well with stats and TEamSpeak as well. Here's their forum link:

Get online. This sim truly shines when flown online.
