On the "Manage Subscriptions" page, it shows a list of the art, writing, forum, etc. things you've subscribed to with a little checkbox to select them by. However, clicking on the names simply checks the box. I think it should link to the person or forum's page instead. I have a lot of subscriptions from years ago that I'd like to investigate if I still want to be subscribed to them or not, and this would save me a couple steps instead of having to hunt down their profile by myself.

Great idea! I've implemented this now. Go ahead and view your subscriptions page and click the "view" link to see artwork by the user you've subscribed to. It wont do this for all subscription types, yet. But all the art and writing ones should work.
