Well, I'm highly critical of flash movies, so a lot of my votes are low. There just isn't much that impresses me, but that doesn't mean it's impossible. Having a dark aura doesn't seem right, because it makes it look like I vote zero on everything. That's not true, but I do vote low the majority of the time. I'd still enjoy the selection option, because I'd love to be neutral. That way, people can have some security in knowing I'm not a zero guy.
Also, the changes have been working very well for me so far, and I think liljim is doing great things for the Newgrounds systems. This site will only continue getting better if more people like him pitch in their expertise.
As for protection and blam points, I NEVER get blam points, but I know I contribute, so I'd like to have recognition.. that sounds neat. Protection points, however.. how do they work? A counter to blam points? That's like another aura. People complain about auras, how will their blam/protection record make them feel?
Good Ideas, but make sure you look at pros and cons. I'm sure it'll all turn out great. You guys always figure out how to do it just right.
