Hi, I'll give you a complete overview as I can.
The url is morethantv .me, you can check if something is working or not from this link: mtv. trackerstatus .info
The situation si that they updated website code, tracker code and some other internal updates. At the moment you can continue seeding the torrent you was previously seeding but the torrent section in the site is not available, there aren't ETA now. There is also an IRC channel to support users for this migration.
