Sign up for Planypus and start making plans for all your upcoming events. Let all your friends help you plan your events on Planypus too. Planypus will let you and your friends all get together online to plan whatever you need planning.

You post an event and send it to your friends. Then they come to your event page and make changes to it. They can change the date and time and what's going to happen at the event or party. Everyone gets to take part.

This can also be used to inform your friends that you are going somewhere and you want them to join you. Just post what you're going to do and have it sent to your friends. Then they can join you later. Events can also be sent to Facebook, Outlook, Ical, RSS and Twitter.
