Well, finally a full integration of vBulletin and Mambo, and it does not cost an arm and a leg.
These guys (ipmambo, viet & koudnashi) have performed an excellent job of linking Mambo and vB together, using the vB user registration panel as the place to register users through.
Just what I wanted. And you can find out more here
http://www.bbpixel.com, and tell them I sent you!
They were quick, efficient and very professional in thier implementation of it and they resolved problems equally quickly.
I paid the for the full monty, they did everything including customizing the vB template to suit my mambo front end. Cost around 80 US$ and from my point of view well worth it.
They also offer other options including a 'do-it-yourself' option.
If you want Mambo and vBulletin, or Mambo and Invision Power Board integration, these are the guys to go for.
Well done, and thank you.
