Yes. I do think it is an important feature. In order to make the forum live, to make more users online for a long time, I think we need to add some interesting features. The most important phenomenon is that most of the users just log-in the forum when they want to ask something, then they leave. A interesting feature should handle this problem. For example, if I want the users can pay the others using their reputation to answer his thread, how can this be done?
Plug-in that can give official posts from the unofficial distinction.
for example, Suppose we have an expert advisory group to provide advice to the students, in addition to our consulting services, other users of this forum have the expertise to advise that we look, how we distinguish topics and posts them that students easily understand the distinction (age group 14-18 years old)?
Have users in the expert advisory group show a badge denoting their status. That might be enough.
