What is the alpha site to report bugs and feedback...I can't find it

If I could have just one thing changed, it would be having bigger fireteams. I am loving the game so far, I just want to enjoy it with more friends than just two. Its a big turn off for me not to be able to play a game with my friends. That, or allow us to join our friends 'server' even if not on the same fireteam, so we can still play together. This is a big pet peeve of mine in games, when its not possible to play with friends, or when its difficult or awkward to do so. I had 10 friends playing the Alpha last night so we all got into a voice chat and talked about the game as we played. We were on different servers and different fireteams so we were all doing different things, but at the very least we were all able to talk to each other while playing. How much more fun we would have had if we were all on the same team, or at least in the same server, exploring and playing the same missions together. If I am online with 5 other friends, for example, we can split into two separate fireteams and that's fine, [b][i]if[/i][/b] we are able to join up in the same free roam session and play together. But currently, we can't do that. Not reliably anyway. My opinion is that fireteams should be at least 6 players maximum, if not more.
