One of the first thing you (should!) learn as a programmer is: don't reinvent the wheel. That's a big part of what procedures, oop and general modularity is about. Mike's program, however useful, bring functionality to us that is already present on the web. Sharing a text document with someone is hardly new ... Check out EtherPad for quick fix: http://etherpad.com/ Really quite useful, and works at least as good. Google Docs is free and can be used for the same purposes *with* authentication.
