To try and streamline the XDDN groups around Australia, I have been working with the organisers of the other cities to create a few central locations for everything.
For those unfamiliar with XDDN, it is a usergroup I run that focuses on UX, Design and Development on Microsoft UI platforms. Such as Win8, WinPhone7, HTML5, etc.

The main reason for moving everything to Meetup is that it allows everyone to easily see upcoming events and get automatically notified when new events are created.
Having XDDN on Meetup.com also supports my other goals of getting more people involved with their local development communities. Joining the groups will allow you to easily find other local groups that you may want to attend, such as Agile or Alt.Net groups.
Please join the group for your city, as the old event sites (such as EventBrite) will be slowly decommissioned over the next few weeks.
