To answer the Linux/Win question, our site
www.feds201.com runs on a Linux Webserver, but i do all design on my home computer which is windows and then just up-load. Just go to
www.php.net and
www.mysql.com and download a Win 32 binary. They are self installers. Also, you'll need a webserver (with windows either IIS or PWS, but i use an apache webserver win32 binary download at:
www.apache.org ) If you're running windows, many files will be .tar or .bz or.bz2 so be sure that you download a de-compressor for windows. I use 7-zip;
http://www.7-zip.org/
I'm not sure what übergeek's uses for the main page (i'm guessing flash mabey with dreamweaver??) - sorry to lazey to read the source code. But, they use phpBB forums (which are free and
www.feds201.com uses) download at
www.phpbb.com They are all opensource and even if you don't know php, (which you should learn) they have a great phpbb community which have all different kinds of hacks.
I hope this helps
