<< I suggest you check the archives for successful paper and
sizing formulas (some think you don't necessarily need a size) and add the
kit to that. Find a repeatable light source (again in the archives or email
me for a few ideas)

I'd be happy to answer specific questions if I can. It's a great process.

Well, the FAQ are now in the form of WEB page, and I can't (or maybe don't
know how to download the articles or part of an article). I actually like the
old format better (when you can send a request and have the FAQ sent to you.
Can one still do that, by the way?)

Scopic's book doesn't show how to use a light box as the light source. I have
a 12x18 light box for viewing slides. It has color-corrected tubes in it
(5000 deg. K). Can I use it for the light source? What is a starting point
for exposure time?

Also, do I have to worry about the unevenness of the light? Since it has only
a frosted acrylic over the tubes, the light is brighter near the tubes. Do I
need another piece for acrylic so that the light will be more even?

I am thinking about laying down the negative, sensitized paper, a mouse pad,
a piece of glass or plywood, and finally a book (for weight) over the light
box. Do you think this will work?

Another question is how can I walk out of the darkroom when the paper is
being exposed? Do I have completely light-proof the exposure system?

Thanks in advance for any help/suggestion.
