Hello,

  I host and maintain an open source solidcoin<->bitcoin exchange ( https://moonco.in/exchange/solidcoin ) and a namecoin <-> bitcoin exchange ( https://moonco.in/exchange/namecoin ).

 We charge a 0.2% fee, have no withdrawal fees (beyond the transaction fee which goes to the network), have an API, a chart, and a live calculator on the trading page.

Edit:

Our solidcoin exchange will still remain open long as there is interest in trading solidcoins, moonco.in has nor wants involvement in the drama surrounding solidcoin. I simply want to maintain the code for an open source exchange to be used for cryptocurrencies  and provide a reliable and quality service.

tl/dr We choose this remain open because the community uses it, not because we have a position one side or the other.

 Any feedback is appreciated, we are an open source project and we require input from the community in order to be successful.
