Wikis, Chats, VoIP and online collaboration

I have been using Yahoo IM (xgreekloverx@yahoo.com) to move video and
GoogleTalk (matthew.horvat@gmail.com) for the voice. This combination
seems to be the best for seamless communication. Skype is also a
method, but the voice seems odd at times.

For Wikis I use PBwiki which makes creating a wiki as easy as making a
peanut butter sandwich. The formatting seems to work better than
others that I have tried. This is a great tool for mobile development
or collaboration.
