I know there's going to be a larger world, so everyone should be able to have their own house... but that doesn't mean some of us won't enjoy sharing anyway!
Currently Jeff and I share a house because in the mad dash for the last properties we didn't have enough currants for one each so pooled our resources.
The problem is, every time I want to go and tend my patch in his garden, or get to my items I've left littering his floor, I have to bother him with a knock. If he's had to go do something else for a while, then I'm stuck.
It would be really nice to have a way to setup "house mates", a person (or persons) who you give permanent access rights (which you can obviously revoke if needs be). Then I could stop bothering Jeff and we could live together happily :oD
