Forum Categories
Installation and Configuration
When importing 'global discussions' from a Ning archive you have two options.
1) Import them to the Jamroom Forum module
2) Import them to a Jamroom Group
The differences are that the forum module provides more flexibility for managing categories, topics and posts but user posts on topics are 'flat', ie. one after the other by time posted, whereas group discxussion comments can optionally be 'threaded'.
Whichever you choose, in Jamroom, all forums and groups (as well as all other module items) belong to a profile, so I would suggest that prior to import, you create a profile called (say) 'Community'. Then you can configure the import process to allocate 'global' discussion to this profile's forum or group.
Hope that helps
