Collaborative office stuff? Do any of you have some sort of collaborative software for your office that is more formal than plain old Google Docs? Or do you use Google Docs professionally? →[More:]We are constantly trying to schedule people for projects, work together on lists, etc. but there is so much "okay, you do this half and send it to me, and I'll do that half and send it to you" that it drives me nuts. This would probably just include a word processing thing and a spreadsheet.

Thanks!
