MeetUps are FREE and open to everyone, even if you're not registered for ApacheCon. Come and join us to participate in your favorite project, or to discover something new! Be sure to checkout the wiki page for each meetup and signup your attendance.
Meetups tonight include:

* Apache OpenOffice.org in: Salon A
* Apache TrafficServer in: Salon B
* Apache BigTop (Incubating) in: Salon C

MeetUps give Apache projects the chance to organize their own events, and talk about what they're interested in. MeetUps cover everything from developers attacking a bug list, to user stories and sample applications, to introductory nights to introduce new users to a project.
More details about Meetups are available.
