Adrenachrome, music in sigs is against the forum rules. As for the banner, I just ignore it; since Chruser has already allowed it and has already been paid for it, it won't be going down untill its time is gone. It's like a commercial. Do you really think that a TV station would stop playing a paid commercial just because you call them up and say it bugs you? Just ignore it.
Here's a constructive idea: Make your own pro-bush or whatever banner and have Chruser put it up for $10 and link it to whereever you want.
It's accepted as long as it has some kind of play controls (likely Flash) and doesn't auto-start.
