There wasn't a specific rule against it at my school either, but it wasn't exactly celebrated either. My sorority accepted RA's or potential RA's with the understanding that both sides would work together to accommodate one another. From what I gathered of the other chapters, they "frowned" upon RA's... take what you will from that statement...
The RA's that were lucky enough to have an RHD that was cool with being greek, there weren't problems, but like other's reported, if the RHD wasn't ok with being greek, there were considerable problems, and I had a few girls, one being my one of my littles, resign from their position due to this major conflict.
