I just started playing tonight, figured out how to go visit other towns and clean but I didn't leave a message. Yet I find that some of these players came by to reciprocate. So my question is how did they know? I would like to do the same (I did finally notice the arrow on the wall messages left for me so I could go clean for them). How do you know who visited and cleaned if they do not post on the wall?
Thx,
Barb
