If you don't, you really should. I am a part of three different "groups" I guess you could say on there. Two of them are for groups that I belong to on Etsy, but one is open to anyone! It's called "Buy it from a Mom".
By It From A Mom is an open group which means that you can be a mom selling items or just someone who wold rather buy from a mom than buy from a store-chain. I know that the mom that started it sell Avon, so there are all kinds of things that people are selling on there.
It's a lot like Facebook or MySpace or the like. The biggest difference is that you have a different page for each group. So my Etsy Kids page is not like my Cafemom Etsy Moms page or my By It From A Mom page. But then again, that's okay too. I have my widgets on there from Etsy so that doesn't have to be messed with after it's set up.
Anyway, think about joining this group, especially if you are already on there! There is a badge on the blog where you can join! Hope to see you there and don't forget to mark me down as a friend!
