Thanks for your response!
So I would start writing the stuff... but I'm afraid it would be then limited to the functions that I'm using for my site, and of course some explanations depend on the theme that I'm using
Thanks will give this a try.
Also considering having the WP site in an iframe on my NBB homepage, then styling both to match. However, with this option, I'm not sure how best to setup SSO. Is there a way to use NBB as Login, Registration and Profile and pass the info to WP. ie using NBB as the AUTH provider?
