Lots of things are do-able if you have unlimited time and resources, we do not.

I cannot see a time when this will happen, sorry.

it could be done if it was just a CSS / Image replacement - but that is not the case

some of the styles released here requires template edits, some are written badly, some are outdated (even if it's current)

Yeah, like I said, it wasn't anything I thought was simplistic. Just doable. The idea I had was members upload a ZIP file and the contents are extracted to the right place. Rather then a demo board for each style, I imagined a demo area for all the styles. The key thing was just being able to interact, at least in the styles forums, with a given style displayed.

But, just an idea. At least the idea is out there and maybe someday you'll be able to come back to it.
