Wouldn't this be simple to do using the functionality provided by David Cramer in his plug-in DB Post Types?

wpForo doesn't use Custom Post Types, this will not work.

I'm sorry, apparently you haven't read what that plug-in does:
"Easily use database tables created by other plugins or an external source, as native WordPress Post Types with no data duplication"
I hope you'll have a second look at what that plug-in achieves.

Is it possible show all posts from categories and tag pages  as randomly? I am using newpaper theme from tag div and the theme just  alow random pages, is it possible modify the code? thanks

@Robert is this still on the roadmap or has it been descoped?
