Mashable has a great little piece on how to plan and promote your next event with social media. I particularly liked this paragraph:
“PBworks: The wiki is an ideal platform for planning events – it’s easy to add notes, edit information, and organize content. Both mediawiki (the software that runs Wikipedia) and PBworks (formerly PBwiki) are good choices, but PBworks has been a favorite of organizers because of its business features, better document-sharing features, and RSS notifications.”
If you have an upcoming event, don’t forget to make PBworks part of it!
