Few possible competitions
These are just very basic ideas I thought of..
1) Design a portrait competition. winner will have their designed portrait added to the ingame options, and will recieve 500 diamonds
2) Everyones talking about prose, so why not poetry.... Just to test it out and see what happens.... poetry related to season, best one wins x diamonds
3) Design a theoretical building... best idea gets kudos from the devs and x diamonds
4) Community managers/people who run these things, come up with a theoretical scene (you are stuck in a forest with a knife and a blah blah blah), people sumbit responses, best ones win diamonds (possibly donesimilar to the winter story in the submissions cannot be seen once submitted)
again, these are very basic ideas, but I put them out there seeing this thread is starting to become negative (sorry for english)
