*mental note: continue to use Good Charlotte in your themes* That's too bad, though. Today I had a really good idea for a new non-GC theme, but since LeopardBritney loves my GC themes so much, I may just stick to them.
Thanks to everybody else for their opinions. LeopardBritney, just FYI, Good Charlotte has more meaning in my life than you'd ever imagine, and they play a big role in why I'm still alive today, which leaves you with two options: Learn to accept it, and get on with your life, or learn to respect others' rights to display their artwork in their signatures, and get on with your life.
Actually, using secret option c: All of the above, would probably do you the most justice in your life: Accept what you can't control, and respect the voice of others.
