Okay so the first suggestion is a chat panel in the social window so you can chat with the neighbours who are online, leaving a msg on their wall just seems to be a little too impersonal and hard to keep a conversation going switching between your island and your neighbours.
The second suggestion I'm hoping you might give some thought is a confirmation button for the spending of gold, simple "would you like to spend this gold" [yes/no] would be awesome.
I enjoy this game and I appreciate all the work you've put into it, thanks for your time.
