I remember when they started allowing us to submit our own icons, that was such a game changer. So many of us got so into it. I actually was backing up my Photobucket and I stumbled across the ol' icons I made in MS Paint.
I really enjoyed how Trunks's thread was the main hub in Action Discussion. It was the main place most of us would go back to outside of AIM to discuss the block.
I also missed how competitive things got for posting episode threads and how there could be only ONE per episode every week. Designing an episode thread was what gave me my first experience in HTML funny enough.
