I know Goldie Blair is still active and has done a pie vid or two since.

Who else?

Christina Carter is still around, but doesn't do messy anymore. Most of her videos involve S&M, and several of them are hardcore porn.

Really?

How about Lauren? Or Nicole?

Seconded she was my first WAM crush

Lauren was? Or Nicole?

Yup. She does messy. She's just selective with who she works with (rightfully so) and she also announced that she is retiring so sadly this will probably be the last messy shot we see of her.
