Server dues are $3500 annually. I dont expect the costs to be covered by members or users- as I use the server for two more sites... one is afro's board game and the other is the woodcraft site.
There is another about to be launched and I'll be making somewhere around $2k for designing, building and launching it. This is a new development as the server has been used JUST for "us" and supporting sites. However, it takes a chunk out of the annual dues, so I see it as necessary and required.
So... if I could pull in $1500 annually from selling crap on the woodworking site and donations (and I hate asking for donations... this year is tight or I wouldnt) and so long as $2k a year comes from the other site about to be launched, we're good indefinitely.
I dont think there is need to do a monthly contribution. Maybe we'll do a drive once a year and dependent solely on how well the woodshop or supporting sites do... again, this year is tough where it usually isn't.
