This week’s “MUG Event Calendar” is a busy one as some groups reschedule their meetings for the upcoming Thanksgiving Holiday in the U.S.

Digital photography guru Terry White will visit a Michigan group, one group in California will enjoy a tour of the Prosoft Engineering facilities, while another California group will have a visit from Mac author Chris Grover, and another California group will host Avery. A little farther east, a Texas group will enjoy a demo of printers by HP.

If there is one dominant presentation subject this week, it is iCloud, with groups from Florida, Arizona, the Carolinas, Virginia and beyond listing it as one of their primary topics. Other topics on this week’s agenda include iMovie, Apple TV, Siri, wireless network security, iOS5 and Pages.

“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. For more info on MUGs, and to find the location of the one nearest you, go to Apple’s MUG page (http://www.apple.com/usergroups/).
