I am sorry if this has been already posted but I just can't find it. I just want to ask him a few questions, Thanks! (The beamng.com username not his actual name,)
Depends what you need in particular, each of us work on different part of the game (see wiki page above). In general you can simply post on the forum. Either some other user would reply, or us if needed.
That's not true at all. The EULA states that we do not "own the game" but have paid for a lifetime lease of it.
