They purposely don't have links to them in some profiles if they're faded out like that. To help make it a little bit clearer and easier to understand, I plan on re-doing those images in the next 24 hours. Some of those buttons are faded out even when they shouldn't be so it's all a mess that will be cleared up by tomorrow afternoon.
Thanks for reporting this though. Dig the new sig, man.
