Oh yes, finally! I'm late to this party but it's obvious we really need a cupcake forum!
I've been doing quite a number of cupcakes lately and learn something each time. So thanks for some of these tips! I can't remember the last time I did an actual cake.
Here's a site that has some very interesting recipes...scroll down and look for the "Cupcake Menu" on the right (I think this was posted earlier):

Some sound scary but some look tasty. I've yet to try one one but will soon. (probably the vanilla bean/black cherry ones)
I'm not sure if someone's posted Zalita's link yet, I can stare at these all day. I have. She is AMAZING.

Confectionary House is good for liners, so is Beryls. I recently purchased some chocolate brown(very dark, almost black) and pastel (a darker pastel) ones from the UK. They didn't come out "greasy" after baking. I hate that.
eta: when I post the Beryl's link, it shows up as G lobal Sugar Arts. Weird. Just go to b e r y l s.com
