Ok, I'll see if I have any problems.  What I'm doing seemed like it
might be the wrong way to go, so I figured I'd ask about it to see if
I got any "don't do that" type responses.  Sounds like what I'm doing
is pretty much sane, so I'll see if I run into any trouble.

Thanks for the info.  I'll be back if I have any trouble :)
