Zoho is very cool! I like this a lot better than the PBWiki. It's more user-friendly and offers a great deal.
Not only can you text in chat rooms, but you can also make appointments (and have reminders sent about them as often as you'd like), as well as add notes, insert photos, create wikis, word process, create spreadsheets, schedule meetings, and all kinds of other wonderful things!
I'm glad Zoho is universal, (not just in SoHo)!
