I agree that the layout of the wordpress site would be work better than the existing gbpvr.com. Whilst the gbpvr website has great screenshot images, the only real purpose it serves is to provide 3 links (which on my 16:10 laptop screen, I have to scroll down to find).
I think it would be good if there were:
links at the top to wiki, forum, documentation, donate, download, about.
A description of the product (that avoids using subjective adjectives such as "mature, robust, full-featured ")
News items such as info on new plugins, skins, updates, patches, new hardware releases (such as tuners).
Links to the top ten viewed forum postings in the last week?
Obviously, someone would have to write and maintain all of this ...
