This is a very simple little add-on that warns you when your feign death is resisted. It is similar to FeignResistBell, except this version doesn't use sound but instead relies on visual warnings for those players with sound off.

If you have Blizzard's floating combat text turned on, FRM shows a large floating message when feign is resisted. If floating combat text is off, it puts a message in the UI error frame. In either case, it also puts a message into your default chat frame.
