Maybe we introduce a new game/ event each weekend to keep numbers up. Like a weekly uhc, but it can be like sethbling's building game, or a spleef tourney and implement a donator rank where whomever donates have a special item that helps them in the type of event.
How do you feel about this?
First we have to establish the foundation for everything. Active surveying should be conducted to build a basic idea of the needs and wishes of the community. Once we have a grasp on the situation, we can start planning further - events, games, orgies...
On the notion of
special items that helps them in the type of event, we're not a P2W community - if that's what you mean. Surely there might be some perks, such as taking a second or two off of a respawn timer if there ever were to be such an event or a mini-game, with a respawn timer and all.
      Donator features, as always, will be there purely to make the donators stand out with funny commands and such. I wouldn't mind them having something little to help them get around better (such as 1.2x more mob drops and the likes, for example), but strictly P2W is bad, mmkay?
