But I wouldn't call what happened a few months ago a flaming, Almindhra. If I remember right, a few people disagreed with you, and a couple got a little defensive, but I don't think there were flames involved, if I'm remembering it right.
I think the problem isn't the sigs, necessarily. I think it's the idea of what is basically a one-line spamish post with a sig that's like a dozen lines. It becomes a repetitive thing, especially in the Battle Arena, where people are going back and forth at each other. Some of those pages in there are 90%-95% sigs and only 5%-10% content. It makes it really hard to follow the thread, because who really wants to read the same thing over and over and over...
I think you're message gets lost when that happens. And the way I look at it, the whole point of posting here is to get your message out there for the rest of us to read, and comment on. If the content of your message is more important than your signature you don't want it to get lost, do you?
Think about it.
