Board Game Arena

I think it would be really useful to have sub-forums available for alpha games, so that reviewers can discuss issue with the game among themselves. Shouldn't be that hard to make them available to reviewers only, right?

You know, just in case that people can even get alpha started, which I certainly haven't so far. Would still be great to have though!

No, as alpha games are not available for general BGA users.
Use player group or alpha game forum instead.

Also, almost every game in alpha has it's own dedicated thread within the alpha subforum. So that is already a good place to discuss matters about that particular game.
