I just want to keep someone from surfing. I made up an Email Only account in
Emerald and then I put the Framed-Filter "email" along with the two basic
attributes. I then loaded the filter on my Hiper ARC named "email.in". This
should do it, I thought? I verified the filter with the Hiper Arc and it came back
ok. Of course what I told it to do might not be ok for logging on, I understand
that Hiper ARC only looks at the syntax and whether it is exceptable. The show
session wont work since I am testing this filter and not assigning it to anyone
yet. I think I will just assign a filter with nothing in it except what you have
here. Then I will build on it until I screw up.. Sound like a good idea?
