I am one of 4 co-founders for a Minecraft community that is going live in January. In addition to the 4 of us, we have two administrators and a few moderators.
Founder A is the guy that provides the funds for the server. Other than this, he is fairly hands off unless I ask for help.
Founder B (myself) has been doing most of the work thus far. This involves getting the two dedicated servers up and running which is mostly configuring the servers/plugins/permissions.
Founder C comes and goes pretty much as he pleases. He has mood swings and vanishes for weeks at a time, causing anything he was working on to be put on hold. He's a great guy and can do the work, but he doesn't stick around long before another mood swing hits and he leaves.
Founder D is our advertiser. He's the person that can sell you anything and the reason this server will be successful when we launch in January. Both of our Admins are great people and can handle the in game administration and building we have requested of them.
The problem we have is with Founder C, we don't want to remove him from the servers and has been around longer than I have. However, his productivity is low and the mood swings kill all of our productivity because we have to deal with either him or what he was working on frequently.
I'm looking for ideas on how to deal with this Founder.
