Mayor Clubs — what's to improve

I as well put in a suggestion that we be able to chat from mayor club regardless what city we are visiting/in.
I like the idea of push notifications. I ask for help and hours later someone might respond. Also I suggest a last login stamp shown for each member so inactives can be booted, as mayor's club benefit is only trading without having to be Facebook friends.
Lastly the word filter is crazy. Filtering way too much like: wood, got, full. Just to mention a few.
