Yes but that's exactly the point of it. Member's Only is like The Haven in that it can't be viewed by non-members, but it's different in that it's less depressing. Random Discussion is just that: It's random and very diverse (in fact it's the forum that's the most updated after a day, more than a pages worth sometimes!). If you've got an embarrassing thing to talk about, put it in Member's Only. If it's can't be defined under a subject on WP or you want it to garner a bit more attention, put it in Random Discussion.

I was sad when I found that she left
But then I found
That I could speak to her,
In a way
And sadness turned to comfort
We all go there
