Latest Ning Import module released.
Installation and Configuration
Strumelia - As you are still in development, what I suggest you do is set the name of a new 'Forum Group' in Ning Import config then run the Group Discussion import again (set to 'create'). This will import all that previously went to the forum module to that new Forum Group.
Each 'topic' will be a group discussion with all the posts. All existing Jamroom users will automatically be members of the new group.
You can then run both the forum and the Forum Group at the same time to see which you prefer. You can even set the Forum Group's URL in the Ningja skin settings instead of the forum one so that the forum menu link goes to the group.
