Trade Ogre communicates by Twitter and twitter messaging. They have always responded to me. I questioned them about not syncing they replied that the network seems to be shrinking. I am guilty of not pointing my miners to coal in a while. Difficulty is certainly a lot higher, than when i first started, at the announce of coal. Trade Ogre is a functioning trading platform , and the only place coal is listed that i am aware of. Perhaps we should show them respect and an honest interest in them opening the wallets again, because without them there are no trading alternatives.
