I wasn't part of theSpoke v1, so I didn't see it.
But yes, such a control would make sense. So you are saying this was a public control?
In earlier versions of CS, we had a Subscriptions page in your profile. This allowed you to see what posts (in the forums) you were subscribed to. I suspect since the introduction of Weblogs, Galleries and other applications (such as File Manager, Guestbook, and RSS Reader in CS) that this was disabled in the current builds until it can be updated.
But it was Private (for your eyes only). This is because the list could be extensive (mine was, subscribed to 100s of posts on communityserver.org).
I'll see what I can suggest though.
Thanks!
