To plug my own product: try http://iDoneThis.com http://iDoneThis.com We make it easy to know what everyone is getting done. Tracking and accountability are two of the biggest problems we've seen with remote teams. Often work with remote employees requires asynchronous communication because of time differences, making it difficult to sync up via Skype or Hipchat (two great tools). With iDoneThis, we email everyone and ask what they did. They just reply and it goes into a central place. The next morning, everyone gets a digest with what they did. It's been a big help for us sync up with our remote developers who are freelancing for us. We use it along with Skype, Campfire, Trello, and Google Groups.
