On-line Business Collaboration

I'm very interested in learning more about on-line business collaboration.

There is some software out there which can be used to facilitate this.

If you know of any, please leave a comment and I'll try it out.

Wiki's can be very useful for putting business plans together on-line as well as in actually developing the strategy required to advance the business plan.

Surely there must be a way for entrepreneurs in Kitchener-Waterloo to communicate with each other to advance common business ideas.
