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!
