The 'algo' isn't relevant because Mintcoin is no longer Proof of Work and can't be mined, rather it is staked. However in the history of the coin, Mintcoin had a mining period before it switched to 20%, then the 15% stage came a little early and the coin forked to handle some technical issues. The 10% phase switched without any problems, so the clients can be updated but the core code shouldn't have to be forked again.

RE: mintcoin-central.com, I put in a request for David Latapie to transfer ownership to me, seeing as I have funded the last two domain extensions on the site. I put in a redirect to mintymintcoin.com but this isn't showing for me yet.
