"up4 has created a handy little Facebook app  that lets you easily create casual events and meet up with friends somewhere offline.  With a scheduling calendar, you can pick the day and approximate time for your meet up.  Or you can click the \"add\" button to go directly to the screen for manually entering your information.  Say what type of activity you're \"up for\" and indicate a time and location.  Add any extra information you'd like, type in the names of Facebook  friends you'd like to notify, and post it to your up4 application account.  All of your events will show on your calendar, though there is the option to see these in a list view as well.  See what your friends are up for, and decide if you'd like to join along.  You can also leave comments to hold discussions around individual events."^^<http://www.w3.org/2001/XMLSchema#string>
