Forum:Subscribed to another user's message wall... how do I undo?

I am an occasional contributor to the Avatar wiki. I must have somehow subscribed to Vulmen's message wall. Vulmen gets a ton of messages, most of which don't relate to me. The message wall is not on my Special:Following, and I get tons of e-mail delivered to me that relate to him. How do I un-follow his page? Iggyvolz 18:35, May 26, 2012 (UTC)
