[edit] Tips

Discover places via the 'Everyone' page: you can easily find places by using the search bar on this page. Just type in a description (e.g. restaurant 94310, free wifi, etc.)
Discover places via the 'My Community' page: Invite friends to Rrove and keep track of their locations. Get their userIDs and type that in 'Community Members.'
