Groups on Facebook

I've started making groups on Facebook so I can keep up with how I know certain people. I've made one for Starbucks friends, Hummer owners and fellow freelance writers and it's awesome because it's kind of like a group where you can write things on the group and only they see it but can reply and all that. No one else on your friends list sees the group if you make it secret. Anyway, if you want to make a group just look to the left on your page and it'll say make a group or create a group. The rest it'll walk you through. :)
