After a discussion that spilled into quite a few topics, I decided to take Leknor's suggestion and host a Wiki on my site.
Equinoxe Solutions is hosting a TikiWiki (PHP-based Wiki) at http://www.equinoxesolutions.com/tiki
The basic install is finished but it is still VERY nascent and therefore not set up fully. Suggestions, and comments are very helpful.
I'm thinking for now an Articles section, for articles, and a file upload gallery for "Shared Code" would help. Any other ideas?
Also, would anyone care to help admin? I don't think I can do all of this work myself.
