I have set up my namecoin wallet on mmc-wallet.com and I have pointed Bitminter there. They have loyally been sending the coins off to my wallet, but most of them are not showing up (we are only talking a little over 1 at the present time...oooohhhh...$3.50!!), but I want to understand how I can get this resolved.
Messages to the wallet web site have gone un-answered - you get what you pay for there I guess (free).
I'd recommend not using online wallets. You can download an NMC wallet from namecoin.info. Or you could send the coins directly to an exchange if you just want to sell them for bitcoins.
I would immediately stop sending coins to nmc-wallet.com (I assume you meant that and not mmc-wallet.com). I'd also recommend moving whatever coins you are able from their site. If they are just taking your coins and not answering, using their site is a bad idea. Also they appear to not even use SSL...?
Apparently it's a suspected scam site:
