I think it's pretty clear that the forum is almost empty, a lot of people visit the forums on a regular basis although never post. So I propose adding newer forum sections that don't limit discussion to just the game, sections such as Forum Games, Off-topic discussion etc.
It'd also be nice to have 'Developer Diaries' so players can be confident the game is making progress and the developers have certainly not given up.

Development needs to be more open to the community even if progress on development is paused for a short period of time it should be announced, don't keep the players completely in the dark like many game development companies do, it can drive many players away for example Transformers Universe which for around 3 years barely any information on the game has been released which has only angered it's community and severely damaged it's reputation.
I'll be checking back on the forums daily and would love to be able to post a lot more and have a larger community involved in the early stages of the game.
