“The MUG Event Calendar” is back at full throttle this week, with lots of homegrown presentations and demos, as well as some high-profile guests.

Steve Sande of “The Unofficial Apple Weblog” (TUAW) will talk about Internet safety with a Colorado group, and author Jeff Carlson of “TidBITS” will discuss the latest version of iMovie via iChat with a Portland group.

The Mac App Store is sure be both an official and unofficial topic of discussion at many meetings, along with iLife’ 11 and its component applications. A few of the many other topics being talked about this week include geotagging digital photos, the Apple TV, Reunion, backups, 3D video production, presentations, going paperless and more.

“The MUG Event Calendar” can be found at The MUG Center (http://www.mugcenter.com), an online resource for Mac User Groups. MUGs are good places for making new friends in the Mac community, improving your computing skills, finding solutions to technical Problems, and perhaps locating a good deal on used hardware.
