Thanks. I see another old main stay bit the dust too- Rugged Defence- where LoL I was known as General Mayhem ;-) - from a post here:

I see gamesquad.com is still going (the successor to WarfareHQ?) though TOAW and a lot of other games' forums are archived.
On topic, I dimly remember helping to organize a tournament between Blitz and WHQ ages ago, Sands of Africa or somesuch, using Tobruk 41? So cooperation was/is eminently possible. I was a member of 3 clubs in the search for opponents, rather than nay preference for one over another, though some seemed to focus more on the games I was interested in, like TOAW.
