Well the first thing to do is to update it with patch 4.08.

Then nip over to Hyperfighter and pick up the Hyperlobby client

It seems that Hyperlobby is a more popular hangout for squadrons than the Ubisoft forums.
I’d suggest signing up there under you SL name with RCAF tacked on the front, e.g. RCAF_Cornelius in my case. The reason I suggest RCAF in front is it means our names all get listed together in the lobby which helps to see who’s online.
I still need to look into hosting private games for us on there, so I’ll let you know when I find out more details on how to do it.
I’ve found this add on dynamic mission generator worth it’s weight in gold.

It’s fairly easy to use and gives you and infinite amount of new missions to play

This forum seems to be one of the key IL-2 forums out there so I’d put it at the top of your list if you need help with the game. It seems some people have difficulty getting it to run with Vista and other don’t. There are some tips on the forum here if you run in to trouble.
There’s quite a good general guide here, but it’s a bit out of date now

Lastly this is a link on the Ubisoft forum to big list of other IL-2 sites

It might be an idea to use this thread to add to as we learn our way around the game.
