Approving blog posts
Using Jamroom
Well, as you likely realise, Jamroom isn't Ning and inherently what you are wanting isn't inherent in Jamroom. However, JR is flexible enough to maybe make all things possible with a bit of customisation !!
But before we go down that route, are we talking two seperate requirements here -
1) You want users want to able to approve comments on their blog posts before the the comment shows to the general public
2) You want to facilitate an Advice Columnist
Are these two requirements connected and the Advice Columnist is somehow going to use blogs? If so, how does that work? I assumed an Advice Columnist would be asked a question and he/she gives answers. That's why I suggested giving him/her a forum.
