I've added two new beta servers, so we now have:

uswest.middlecoin.com:3333 in Oregon (same as middlecoin.com currently)
useast.middlecoin.com:3333 in N. Virginia beta
eu.middlecoin.com:3333 in Ireland beta
asia.middlecoin.com:3333 in Singapore beta

They all switch coins, just like the original US server. After beta ends, middlecoin.com will point to the server with the lowest latency to you. So you don't need to mess with your miner config at all if you don't want to participate in the beta.

If you use a beta server, be sure to have a failover server because I might need to take them offline if they have issues.

Also, don't use --no-submit-stale. On any server. When we coin switch with the new non-disconnecting tech, cgminer thinks some shares are stale when they are not.
