Why not just take donation polls and see if you can raise enough money for a server upgrade?
perhaps if you could raise enough money ( x>$7000 e.i. ) you could buy a server and host Feral Heart; although hosting your own at home is not the greatest idea due to redundancy purposes and bandwidth allocation, let alone potential environmental issues (power outages i.e.)
If people pay money into the game, they start expecting stuff. Stuff that isn't happening. If FH gets more money, sure there can be a server upgrade, but what if Kov decided he no longer wants to have his game up? Then all those people who donated lose out. The server is as good as it's going to get without a game update, which we need. It isn't so much about money as it is about the game not moving forward and therefore there is no point in moving the server forward.
In short, the game stopped growing, and now there is no room for new members and we can't do anything until Kovu finishes some work on the game.
