As per the above as looking to convert/upgrade my wwwthreads forum and the Mambo integration does not appear to have been done before. How difficult would this be - not full style integration, just sharing a common login as a start and perhaps having the comments and forum links in Mambo go to Gossamer Forums? Same question if I was to use Gossamer Community (I also have links SQL).

FYI there is a third party module for Mambo integration with UBBthreads but I would really rather go with Gossamer Threads.
