Well said! I think on this page the question "Are you a professional cake decorator?" means are you a licensed baker working in a commercial kitchen who gets paid for making cakes? I would say the majority of people on here bake their cakes in their home kitchens - some of them are allowed to do that based on where they live and sell to the general public - others do it only for friends and family (as I do) and the love of the craft.
As for being the best - just because you're a "professional" doesn't mean you're the best (check out www.cakewrecks.com if you don't believe me). :) I've seen plenty of cakes by people claiming to be professionals that don't hold a candle to many of the cakes I've seen on this and other sites done by hobbyists in their homes.
I love how everyone on this site is so open and giving with their advice, creativity, recipes and support. I've been to other sites where people get snippy with one another and we simply won't tolerate rude behavior or inappropriate comments here! We strive to keep it family-friendly and supportive. Thanks for being a part of our group, Margo! :)
