    I totally agree with you Jenn. How long are they going to be there? Once
    and if you allow this, who knows what there network is like, I do not allow
    unknown networks access to my networks. I will not and cannot controll and
    monitor what is coming acrosss the line. Better safe than sorry. Never
    assume and trust no one, it can save you a lot of headaches. ; )
