Yeah we're set up to let people add/remove tags, I can't even imagine the mess it would be had that not been done from the start. It's just some days getting everyone to remember to add their character tag to a post is kind of a struggle lol. Especially in the network posts, we have an IC network community, since it moves so fast and I think on average we have more ADD people in this game than any other.
I shudder to think about life before tags. I remember being on message boards briefly when I was on GJ/IJ as well and I hated never being able to find anything.
