If you have a distributed team, the old IRC (Internet Relay Chat) can be a valuable tool to host your team discussions, find answers to questions, keep conversation history and a lot more.
In a way, a IRC channel can be used to create a virtual work room with all your team.
If you intend to use IRC with your team, a good idea is to use a software that manages the log of your conversations, since this log can became an important knowledge base that the ream can use later on when they have doubts about what was decided or explained.
