So, we can now block users from posting on our walls, but I can't seem to find a way to unblock them again [ie, I blocked a user to test it out, and now can't seem to find an obvious way to undo this].

Hey- I see a new button and I hafta push it. It's a problem, I know.

Toggle the 'block user' to an 'unblock user' button if/when pressed, perhaps?

I have never even seen this option.

I'd like to point out that I can still tunebox lanky even though he blocked me :D

Much to my chagrin, of course...

we'll be adding an unblock option soon

Fixed! I noticed the big 'unblock' banner at the top of SNYpod's page when I was there a second ago. Thanks Sam!
