Being a flight simmer myself, i don't mind the occassional thread. But this is PPRuNe which is about real flying !
I think that forum readers would find that most PPRUNE members lack knowledge and/or interest so the posts here won't get such a great response.
However, as big red L the moderator said there are MANY sites that cater for this type of thing.
The best ones are:
http://www.avsim.com/ - here you will find info, news on products and thousands of downloads such as aircraft and scenery.
http://www.simaviation.com/ - mostly centers on downloads - think there is a chat room/discussion forum here.
http://www.vatsim.net/ - these guys are the kings of virtual aviation. If you like using the real charts and weather when you use Flight Sims then you will love this. Members use air traffic control like simulators and they provide really realistic ATC services to you while you fly.
Mod: Perhaps you could put a link to these on PPRuNe if you want to avoid these types of threads.
