CLAM can be bought and sold normally at https://tradesatoshi.com/Exchange?market=CLAM_BTC and btcpop.co (need to register to see the orderbook). Volume is slowly picking up but since people rely so much on CMC, they don't really research about exchanges that aren't listed.

Note that TradeSatoshi has its CLAM/BTC pair "listed" but "not verified". Scroll down on this link to see it https://coinmarketcap.com/exchanges/trade-satoshi/

TradeSatoshi isn't available in the US or Japan (and other more obscure countries such as Iran or Syria).  
Btcpop.co doesn't have any country restriction to my knowledge.  

Please Doog and other people responsible, share the info. Currently we don't have any news on the "Xchange" as well except from when Xploited and BAC shows up in the JD's chat.  
Update your FAQ/Website/Announcements. I know you guys are working hard on the Xchange but you're currently letting things die after Polo's delisting.
