I used to be an Ambassador on the CCA website. I loved it over there and there are tons of really wonderful people there. Barbara L, Dina, tancowgirl and I all migrated here and found our true home though.
As with any place there are pros and cons. For me, the money was an issue. I wasn't willing to fork over more than $500 to become a lifetime member. I couldn't see how they arrived at that number in light of the exchange rate. I tested a few small things and was generally pleased with what I got. I LOVE their magazine and some of the recipes from it have become staples in my house. (After modifying some of the recipes I may have even posted them on here!)
It is worth a trial run for anyone who wants to give it a go. Their stuff is good quality and the magazine is mouthwatering. Their site is not as good as ours, it is difficult to access sometimes and their archive system is nearly nonexistant. The only reason I gave up on their site was because my computer HATED that website and would either not let me on, or would crash when I DID get on there.
