I am so confused

I'm familiar with scripting but not fluent in it. I want to use your wblog but everytime I get things set up it flops. I am really confused as to the setup instructions in the cgi file. sigh, maybe I should just try a different program, but I like so much how you have it on your site and the ability to use somthing similar is just toooooooo tempting to let go completely.
I was also wondering how I might set up several different journals under one domain on a server? Different interests require different journals. ANY help is appreciated - thanks, Anon/Tervnut
