I dunno.

In other forums I've seen, the sig is nothing like all the banners we have around here, so whatever little saying we have down there is just like a signed post. Or, uh, a signature.

I used to do a lot of crappy discussing on sites that are, like, nothing but EoEo *gasp!*
And there I quoted The Pumpkins:
Your Strength is My Weakness;
Your Weakness: My Hate.

And that's usually strong enough of an identifying sig, if you cast aside that my posts aren't so much factual combat but blind, raging emotion and opinion based on ficticious anecdotes.

(SPOILER)In other news, I am incorporating a lot of spoilers in my posts these days. For no good reason.
