selling dicecoins.com , let me know your proposal .
It seems like a nice domain so please let us know how much of a price range we're looking at here, so that people can actually make offers based on that. Also, i'm assuming that escrow is accepted right(It should be for every single transaction on this forum).
Also wehn you start an auction, make sure you list all the details. Otherwise people don't know how to bid etc. List the increment, starting bid, reserve price, and when the auction ends. That'll definitely help you attract a lot more potential buyers than just a sentence in your OP.
Good luck and hope it fetches you a decent sum.
