The same term being used in two different areas, let the confusion ensue!

There are five core sharing areas in a Ning social network: Blogs, Forums, Videos, Photos, Groups.

The term "discussion" is made confusing because it is used in both Groups and Forums. They are however completely separate from each other. I don't have any real 'super-tip' to telling the difference, but just keep in mind they are separate. Group discussions will not appear in the Forum discussions; and Forum discussions will not appear in the Group discussions.

Here are the most visible difference to help distinguish:

Group Discussions:


Forum Discussions:


Another difference is that discussions in the forum area allow you have a category.
