Petals Around the Rose: Fraternity Register

Great little puzzle. It took me 10 minutes to solve, and i've since passed it on to a couple of mates who are still working on it as I type. Kind of annoying when you're expecting it to be something a bit more difficult than it is. I think we tend to look at something and if we can't work it out, we jump our thinking UP a notch instead of down. Puzzles like this work solely for that reason I guess.
