Rick,

Browse thru my website. I'm working on what you're asking for - and if there
are holes, I generally write / fill holes on the fly. So ask questions when
they occur to you. Start at the Welcome page, then look at the Tutorial
selection. And follow the links.

As far as a solution to your monitoring your son's Internet use, I would think
about that for a while. This is a techie forum, and we do like to use techie
solutions. For human relationships like you must surely have with your son,
though, you might want to consider a little trust (and occasional random
monitoring). And keep his computer in the open, not locked away in his bedroom.

Many parents, asking for help here, find that periodic honest talks with the
kids works wonders. With the right router and router log, you can probably keep
track of what websites he visits anyway. And being realistic, many parents find
that any electronic solutions, used without backup, simply motivate the kids to
learn how to bypass them. Which is good if you want a teenage computer freak,
not so good if you want a normal (are there any?) teenager.

But don't give up on the Etherboss product! Give them a chance to make it work.
We could both benefit from that. And I will look for alternate products, which
I know have been discussed here in the past.
