Thanks for the welcome, Vovolov, and for taking back in your hands the admin of this wiki. I expect this to become quite a burden for you as things ramp up, so... thanks again for getting into this.
Let me know what I can do to help beside adding more content as info emerge or content gets updated through the beta.
One of the things I can think of that we will need pretty quickly (and I started a discussion on this in the water cooler section) is templates for similar categories of pages. I am familiar with this for full installs of Wikipedia, I am not sure how much control we have in this on Wikia however. I will dig into this in the coming days.
And again, please ping me if there is stuff you need help with.
