Just call them ULL, their admin doesn't have the backbone to really try and push it, and I believe once T-Boy is out of the ULS board they'll probably get even more conservative. There current stance is that they are University of Louisiana at Lafayette and their nickname/mascot is Louisiana Ragin Cajun's or Louisiana for short....So technically they aren't changing their name as they aren't even touching the UL@L stuff. They snuck through an approval to drop the first " 's" from their athletic Louisiana's Ragin Cajun's.
Doesn't really matter though, their main conference media contract is with ESPN and they've apparently created some bad blood with the folks in Bristol and are always listed as UL-Lafayette or ULL and quite often have Lafayette Leopards logo's.
