That's really a good question.
You have actually 55 active Members here in the forum, that's a fact, as you see before.
One of them is my account, but actually, I do not play grepolis on Beta, and a few of them are the accounts from the Beta Team and from the InnoGames Team. Acutally I will wait for the new farming system, but this means exactly, there are not enought players, to inform you about bugs, isn't it?
So I guess, I do not understand the Beta Market. What's is the goal, you will have here on Beta? To destroy bugs?
Sorry, but I really do not understand it! Is it possible for you, to explain the tasks, a Beta has for the main game?
