sonic,
good question, but trying to design a template for 100k+ users would be a cat fight. the template you have now is fully customizable, and the templates directory with all of the css files that control the aesthetics of the site are very well written.

im sure gorpus will have something our soon, and there was one other fella who was releasing some free templates, only problem was that they were not ported to orca, so they didnt work out too well.

Regards,

DosDawg

I am working on a free D7 template thats the sort of thing your after. when its done i'll give you a download link
