What is the "Orangeboard", and how do you use it? Answered

It's the closest you have here to a "wall", where folk can leave comments for you, or you can leave notes & announcements that don't warrant a forum topic.

One big benefit of your Orange Board is that you can delete comments from other people without having to go through the flagging process.

It's basically a "forum topic" attached to your own profile. I've just made a rather pointless comment on yours :-)
