Finally, I almost happy with the balance, and even though I still have some points in my list, I'm considering the beta stage of the map development completed.
Some people have ideas about throwing a tournament. We just need to discuss it.
We could try to discuss/plan/organize not only the tournament, but maybe everything MnM related stuff there. I like the google groups thing less and less, and probably will move to that subreddit completely, and will reference it from the map description.
Why I like the reddit? Clear and light visual design. Convenient browsing. Multilevel comments. Everybody knows and trust reddit, and have accounts there. Easy-to-remember link, that I could place on map's loading screen (cause ton everyone even notices map's link).
