I was looking at some old forum posts and it said Mary Alice from Ace of Cakes posted here? Is this true? What did she say? How can I find it?

It is true indeed. Just do a forum search for ace of cakes and you should find a few loooong threads she posted on one of those, and a few others I can't recall right now.

Mary Alice is the red-headed receptionist who makes Duff keep his nose to the grindstone; Mary Desmith is a very talented piper who creates incredibly detailed designs on cakes.

They have both kindly posted on here to answer some of our questions.

What's Mary Alice's username? Just Mary Alice? None of those links were for her, though.

Look under charmcitycakes, that is the one she used and also Mary, the piper posted, she did go by her name and last name I believe, (or something like that). They only posted a couple of times under each user name. HTH
