In as much as the idea sounds convincing, I still think creating an about page wont be necessary. It will make the forum look like any other website out there. If a newbies want to learn they should surf the forum, learning with experience and conversations, that is how they grow. A simple about us page wont teach them how the entire forum works. And as for researchers, I see no reason why they call them researchers if they wont dig and find things out themselves or perhaps ask their usual questions.

Another thing, the forum is broad, the work to combine a comprehensive summary of the forum will be every difficult, do you think new users will enjoy reading a full book before getting to surf around the forum?
