Ironically, Ramsus was last here about a minute before you posted (edit: Ironically he came online while I posted). You can find his forum profile
here. From there, you can send him a PM (forum private message) and find his email address and AIM (AOL [America Online] Instant Messenger) screen name.
You may want to learn how to write your own web pages, depending on your needs. Writing on your own can take time to learn and fix errors (and thus effort also), but grants you absolute control over the pages. Running somebody else's software or using a website creator afford you an easy but less customisable solution. The middle ground is modifying already existing software, although many software creators do not permit this.
As far as I know, the Compendium consists of existing software and Ramsus-developed Python scripts. The forum runs SMF (Simple Machines Forum)
[link]. The encyclopaedia, as you know runs MediaWiki. The Oekaki runs Wacintaki
[link]If you do decide to go the route of making your own web pages, I'd recommend that you learn the following:
HTML and/or XHTML
CSS
A programming language compatible with your host (PHP, Python, Ruby etc,) if you plan to do anything beyond very simple pages.
If you need to maintain your own databases for the pages you write, how to do so (i.e., knowledge of MySQL/Oracle/PostgreSQL etc.)
Oh, and ZeaLitY; I sent that email about half an hour ago.
