One of the things you should be looking at is >>>> Are you a member of their organization (a resident??) If not then it is not for you to use. Example would be, a group of homes get water piped or brought into there property. You in turn tap into that pipe ..... lets say because it leaks someplace close to your property. What the law will say, as a responsible neighbor did you tell the coop about the leak? Knowing that they pay for that water. Or in another version did you tap into the pipe to get water, knowing that it does not belong to you. Reality is you know it is not yours to use. If you should get caught it is hard to claim ignorance if you only pay for dial up and they have some DSL, RR type service :)and you are using it! So you be your own guide there. It is still considered theft of service (Using that which you do not pay for or does not belong to you)... Theyre are numerous tort cases with telephone and cable companies and wireless services that cover this issue, (not to mention federal and state laws that now also cover this issue) you dont necessarily want to be the one that they make the case about :) if you know what I mean....
