All comes down to expectations. What you may think is a great theme, others wont, and vice versa.
We are in the process of developing a XOOPS Theme Forge (which is a lot of work, and not many people contributing), that does have the aim to attract more Theme Designers, as well as offer a place for those interested to organize themselves, as well as their project.
Further (the biggest work load), we will offer an extensive resource collection for anything XOOPS Theme related. There will be an Icon, Image, and Template Repository, tutorials concerning different aspects of XOOPS Theme design, a web guide to sites, we Theme Forge developers find/found to especially helpfull.
You know dilliywilly7, the big problem those people that contribute experience, is the lack of help from others. Here at xoops.org I often feel surrounded by 5 year old "I want, I want, I want, NOW!" (not directed at you!).
Having said that. Developing a theme is currently very work intensive, and unfortunaly, while many business like to use XOOPS and come here asking for help, the fewest contribute!!! A big annoyance to me personaly, but that's just the way life is.
@brash: I agree
And thanks for pointing this out, these people deserve the credit...all though, as you mentioned, there are a couple more, but I'm so bad when it comes to name
