Regarding il2org.ru - agree, this is good place to fly. I just signed in recently and will come certainly come back. Good place to test your navigational and tactical skills. CAS pilots beware: flak is very intense, so don't rush to any "soft" target you might encounter.
By the way, I find this little program very helpful: IL2SFBConnector. It requires manual input of IP addresses, but once done you have full list of servers with all their specs: pilots online, complexity settings, etc.
