Have you ever thought about using twitter to improve communication with your team?
I have been tweeting since early this month and definetely couldn't stop anymore.

When I realized the great concept behind the tool (quick, open and uncomprimising communication), I decided to put our team to try it.
The results after some weeks was awesome. Now we use the tool intesively all day long.
The ability to broadcast information througth the team is powerful. You can use to simple messages like "The server x was updated.", to give advices for co-workers like "be carefull with Visual Studio when you do this", announcements, or to talk about a new solution to some daily operation that you wish to automate somehow.
I really recommend for other teams to improve communication.
