I think this is a fantastic list. I really would like a place for housing. Possibly housing, collecting, achievements as extreme decorating can be compared to achievement hounding.. or housing and events/community endeavors? Especially as they have confirmed gulid neighborhoods will come in later. And I think the aesthetics portion of housing is just as important as getting together and making sensible housing plots for biome/raid teleports, crafting, and fun shit like arenas and skateparks that are very expensive. There we could also talk about other community endeavors like current 'to do list' of influence and guild money, upcoming events, housing parties, blah blah blahh. Otherwise I'm with crake in just stuffing it in tradeskills/resource.
This will become an important part later in the game so we should really consider it. Maybe make a big one that is called housing, collecting, achievments, events
