I have seen some outstanding sites from this post. I have been looking at XOOPS for a week now and it is amazing. I have no background in Php or portal systems just minor knowledge in graphics and html, but I have found the XOOPS system to be a learnable one for me. I have looked at several XOOPS sites and templates in the last week, read a ton of articles, and Jabbas the site you have listed is outstanding. Very interesting the possibilities are endless!
Here is a theme I liked and have just changed a few things to see what it was like.ASWD. Here is a gaming site my partner built for CS and DOD R.I.P.
