is cmc.ltcoin.net pool active now? The stats seem to say so. I've never mined there before, what is the connection string for cgminer?
Yes it's active and the current blocks are confirmed after a couple of invalids. Can't say anything about the subsequent Orphans.
Connection string can be found on help page
cmc.ltcoin.net:7721
OR
cmc.ltcoin.net:6621
(It's no stratum server)
