Many of us are part of teams which 'span the globe'.
My idea is for a member's location be part of their details, (along with their username and avatar), whenever they make a post on the team's message board.
Yes I'm aware, it could be argued that if you know your team-mates well, you will already know their locations, but this doesn't apply to new members.
Messages such as: "Goodnight everybody" or "It's hot this afternoon", which can be confusing, particurly to a new member.
