Change Msg Board to a Forum and Bring back Sessions functionality.
The message board is hidden away so that it is difficult to even find it.
I never think of using it because it is not readily available, no links on the top menu or home page unless you are logged into the Media Library.
Furthermore, the problem is the message board is poorly organized and does not have much functionality. It should be like a forum with categories and threads and search.
There are plenty of pre-designed message/forum software templates out there that could be implemented quickly and easily. You don't need to re-create the wheel.
Just pick one and install something. Many of them are even free, or at a nominal cost and customizable to integrate with your website.
Any forum probably also needs more moderators tailored to specific subjects and strong security.
2) Note: The sessions have been dying too. Because it lacks functionality or Indaba took away key functionality that used to draw people to use the sessions.
We used to be able to see what sessions each person is working on. Now only a few hot sessions show up. There is no motivation to start a new session to collaborate if no one can find you.
There needs to be a better search, too.
In an effort to phase out the legacy site, we've begun slowly removing functionality. Soon the media library will be removed, and sessions will be revamped into a new product.
