Hey there Trout!
As for Hyperlobby. Look through the players list for the "DD_" in front of someones name. If you see one, click on it and add it to your friends list. Then you can pick "display player game information" & join the server they are flying on.
The first thing I do is check our TeamSpeak though, to see who's around. Then if no one is on TS I'll get on the TS for the server I join through HL. Thus if you find me there, but I'm not on our coms, check the one for the server I'm on so we can communicate.
Some nights it's hit or miss, but keep looking & you'll run across one of us there.
Oh, and if your around NOW. BA is hosting COOPs as I type. Get on the Dogz TeamSpeak & they can give you the address to join.
I will be joining anyone who's left in about an hour or so.
