I’ve done it myself. Like a page on Facebook and never went back, or hid it from my FB news feed. But for giveaways it’s a bit of a problem if the winner can’t be contacted.
I’ve decided to add an email sign up list to my Quiltboxes.com page. It’s at the top right of this page. Just name, email and state (because I think that’s interesting info) are all it takes. And conformation that the email is real. It’s a “bar” you have to get over to get in on the goods. You may get an email a couple of times a year about new products or specials. No frequent big mailings I promise. -D
