Without NPC or School backing, it is dead in the water.
NPC beleief of not adding another Womens Greek Org until the current Chapters are up to Mememberships will always hold New Orgs Back from coming on Campus!
The last school I heard of was Shorter College in Rome, Ga. wanting and asking Nationals to come on as there were only Locals there!
While a lot might depend on the size of the School and any affiliation, it depends on the local attitude.
Look at the Ole Miss. thread! The Old Line Soroities are so entrenched there taht it is almost impossible to have a new group start there!
