The node is back up again. The best blockchain is the same one as the blockchain explorer.

My plans for the future: Slimcoin is a Peercoin fork. I tried to merge it with Novacoin before but Novacoin is too different of a project to be merged at this point. There is a project called Peerunity which is the more maintained and newer version of Peercoin. I will try to merge it into Slimcoin. I will obviously test the newly merged client but hopefully this merging will solve any bugs.
