reseller not much unless they actually wanted to develop it - at most $75-$100
I dont think you would be able to sell the name on to an end user.
Developed the name would be more valuble depending on how the site is developed / member numbers / visitor numbers etc, appraising a name that *might* be developed and placing a value on it is pretty hard, but the right purchaser would probably spend anywhere from $500 - high thousands depending on the site as I said, but the name in it self wouldnt be worth much without great dev work.
