Wiggio - Making it easy to work in groups

Wiggio is a free, online toolkit, developed by students at Cornell University to support groupwork. From the site:

Wiggio lets you use the following group tools, and it's all for free!

• Messages— send mass text messages, voice messages and emails from wiggio
• Calendar— keep a shared group calendar that will send you text message reminders before all your meetings, practices, rehearsals, games and other events
• Poll—survey your entire group and get their responses as they answer
• Folder— dump all your groups’ files into one folder and never send another attachment
• Meetings— never walk 15 minutes through the snow to get to a 10 minute meeting again… setup free conference calls and web chats on Wiggio
• Links— keep a shared favorites folder
