If someone wants to go half with me on a monthly seedbox bill to donate to Team Blu, I'd be willing to pay half the cost of the box every month for the foreseeable future.

Whatbox seems to have the most storage space for the least amount of money. And what's more, they don't shut off the box if you reach your monthly upload limit. They only limit you to 5mbps/sec for the remainder of the month, so if that happened, then the torrents would still be seeding without interruption.

I think 1.35TB storage space would be enough to host all of Team Blu's releases so far, with enough room to spare for future releases.
