I've seen it before, and once even saw it done maliciously. If you are serious about the squad, someone has to take the reigns and get to it!
Start a new squad, and add some minor change to the name to pass the filters. Invite everyone that was in the "old" squad. When they log in they will get the system message to join the new squad, and then its up to them. As for the web site, get the codes from who ever was running it before if its a paid site. Log in, delete the whole thing, and change the access codes. If its a free site, start a new one.
For the squad in the game, set a squad night and get everyone there. email is a wonderfull way to set things up. You can use an email group like yahoo offers if you have to many names on your email each time. DOn't just site there wiondering about "whats going to happen to our squad?" Make things happen !
