Step 1: Show party frames as raid frames. Oh, excuse me, I mean “Operations Frames.” At least that way it looks more grid-like, and your own frame also shows.
Step 2: Right click on the little “people” button on the top of your “operation frames” to bring down the “unlock” menu.
Step 3: Move that sucker wherever you want. Then you can right click on the little people again to get a menu to lock it back down.
Hopefully this will help you this weekend. Happy beta-ing!
