I am planning a Liquibase Online Meetup for July 28th, 2011 at 12:00 US Central Time (GMT-5).
The plan is to try the group chat functionality of the zoho platform this forum runs on. From what I can tell, that means that if you are interested in joining, you will need to send me (firstname.lastname@example.org) your email address and I can send you an invite.
If anything changes in how the meetup will be implemented, or any other related announcements, I will update this thread.
Let me know if you have any questions, and hope to see you there!
