I read somewhere on one of the discussions, someone said that it would be a great idea if you could subscribe to someone that you really like, every time that person uploaded an image, you would be notified just like a regular subscription or PM.

I hope this idea goes through and becomes permenant, it'd be great to subscribe to someone so you know when they have uploaded a new piece, as for when you get the subscription, it would say "NAME" uploaded "NAME OF WORK"! Just my thought.
