I just joined u2christians. It is small and has been near dormant for a while.
I'm an atheist who loves the spirituality embodied in U2 and their songs. u2christians is a community that welcomes all and right now is starting some great activity that discusses how U2 and their music has affected people and what it means in their lives. I'm spearheading this movement, but who starts it doesn't really matter. It's the thing itself that does.
I wholeheartedly invite anyone who reads this over to u2christians to participate, lurk, or just hang out.
