AFAIK ... open.btc is run blocktrades and they are currently having an issue with their backend.. All I know is that they are integrating ETH currently and run into a problem that will hopefully be fixed soonish
on openledger.info there is a chatbox. it shows "online" i tried to get response here, but it seems fake. i would not suggest to present somekind of service if you have no one in place.
but i learnt a lot today, how metaexchange can improve our service.
not running properly bridges and gateways should be addressed if we talk about, why no one is using bitshares. if i were a new user i would already lost my trust, because if i don't know this forum i can'T find information about how to get the support i need, to get my coins back.
