with supernova not supporting XCN after the end of the year. are their any other active pools?

i have tried for a few days off/on to connect to the only other pool listed in the 1st post with no luck and am unable to find any others.

is solo mining my only option? fairly new to the whole mining world, and still dont get how solo mining rigs "talk" to others to get or add their work to the blockchain...
but that is something to look up another day...  right now though just wondering about XCN pools.

TIA
