I have never had a charity rookies before, and only been a part of 2. What arr the rules, if any, of hosting one?
Can you grab a game as soon as its free and hope you are first?
I see most of the time they are done to help with colour levels or to celebrate reaching a game milestone . Is my next level (blue) and my next milestone (50 games) too early to host charities?
And finally, if you have invited friends, how long is a good time to wait for them, befirebyou open it up to the general public?
50 games is too early, id say every hundred games would be okay. A blue charity is kind of early too but if you get 12 other people to join for you it'll work. Just make sure you have at least a few people definitely joining for you before you claim one.
