My friends and I run a little (4,000 users or so) free not-for-any-type-of-profit-whatsoever public chat network. The available file sharing protocols allow our users to share files amongst themselves directly (their content never passing through our network servers). With the SOPA etc type laws being enacted, what type of legal disclaimer can we post to protect ourselves? We all donate our servers and time to administer the network and were hoping an attorney may be interested in writing a disclaimer for us to help protect us against any copyright problems. And finally,we have no way to know exactly what files are being exchanged amongst our users as the protocol connects the users directly to each other bypassing the network servers completely.
