Well I have a bridge on my site so until I get another vB for my other site I won't have much time to work on a non-bridged integration.
However I am in the process of working on the pm system and the profile system.
I have both using the same database.
Yes you can use PostWrap to display vB within PostNuke there are other ways to accomplish this as well. My soultion is not using postwrap.
You will all be able to see it when the site is finished, unless somebody would like to donate an extra license for me to use
Until then stay tuned.
