Problem with Forum as group work around
Ning To Jamroom
Having the 'forum tabs' for newest, my posts etc. on a group discussion page is doable but would require some custom template work. Not too difficult to do if you've worked with Jamroom templates before and know a little bit of html. I know that maybe doesn't help you Perrie but mentioning it in case any other ex-Ningsters who have done template work have the same issue and may be able to help.
The other thing to consider, that may not have been mentioned here before but is something I've noticed after months of working with Ning archives, is that archived comments on any one Ning item are limited to the latest 200, so if you do have 300+ comments in a group discussion on Ning, you are only going to see 200 of them on Jamroom. It may be that you can ask Ning to lift this capping?
Another thing I've noticed in the archive related to this is that although comments may be threaded on Ning, when archived, they are 'flattened' so that any child comments are archived sequentially after their parent comment, and this is how they are imported into Jamroom. Their is no information in the archive that can allow them to be automatically re-threaded. Sorry, but its yet another anomoly of the Ning archiver that we have no control over!! So the upshot of this is that if choosing to import Ning global discussions to a group and not the forum just to get threaded discussions, they will only start to be threaded as new comments are added.
Just mentioning this now in case it affects your decision about this.
