The legal issue is still very real.No. They aren't really.
Until Bob, who despite the contributions of others, still owns the legal rights to the Portal, gets the idea that it'd be really neat to charge people a five dollar registration fee to acess the portal. This incurs not just financial responsibility for the domain, but also grants the owner a near-impossible-to-dispute claim to any profits. Maybe the Admins gripe and get a small piece of the cake, but this says nothing of the members...Bob owns the web space and domain. That's all he owns. He can put on whatever content he wants, so long as it is legal. Why would anyone charge an access fee? At this point, the rational people immediately cut Bob out of the picture and either move to dissolve the ring and found their own or they simply move to dissolve.
And that's just one more example of a legal conflict.There isn't anything legal about the conflict. One person is being a dick with thier webspace.
1. The Portal must have a ToU which protects the rights of each board and its members. This can be supplementary to each boards own ToU but serves to protect against Incorporation.You have no idea how legal incorporation works. You can't legally incorporate anything without filing in a valid state. http://en.wikipedia.org/wiki/Incorporation_%28business%29
2. It can't be a webring. Believe it or not, that incorporates us. Especially with a wide-distribution of funds going to pay for the thing. You may not believe it, but this will remove a certian amount of independant idenity. This is not a 3rd party showcase, it is a Portal (a term I did not chose to use).
All of your legal concerns are bunk.
