I have been going through and deleting unused lots in some of my other worlds, to make space to add community lots. (E.g., I have literally never once used the gym in Windenburg, and knew right away that I would replace that.) So I've also given some thought to which community lots I might want in certain neighborhoods.
I have a sim that I created a while back that I really like, but I wasn't sure what I wanted to do with her/what I wanted her life story to be, so I haven't played her yet, but it turns out she should be a great fit for Evergreen Harbour. There's not really much else I can do to get her ready, though, until I actually have the pack.
I've also been thinking about which Neighborhood Action Plans might work well in which neighborhoods. The obvious ones are the arts-related plans in certain neighborhoods in San Myshuno and Del Sol Valley. But I'm still working on that.
I guess I should probably take another look at my eco-commune on Sulani (they are definitely voting for free love! :D ), to make sure they have empty spaces on the property for solar panels and water collection, as well as some of the other new items. I mean, in general, that's a pretty good idea, if you know you have certain families that are going to want to brew drinks or make candles, etc., now is a good time to do some property cleanup to make room, so you can just pop the new items in once you have them.
