Thank you very much joel, that's actually very reassuring because you've hit the nail right on the head. (bad pun intended but too apt to not use)

I do feel completely phoney writing about being good at what I do, it seems like boasting or something.

Incidentally, most people require secret rooms to hide paperwork, computers and valuables in, nothing more interesting than that.

Hopefully it will be okay to post what I come up with in the forum next week and get some feedback.

Shanna :-)
