A "Grab button" allows people that like your blog to post said button on their page. This button is linked to your page and anyone that clicks on it will be directed to your blog. (Great for getting more traffic!)
It's a way that bloggers can help promote other blogs & show which blogs they read.
My post above on how to make one is 10 easy steps...if you make one, let me know & I'll be sure to grab it!
**Also, I tried to follow your pages, however, you do not have the "Followers gadget" on your sites. You can add this gadget on Blogspot by going to the section where you would edit your blog, click on "Layout" & then "Add a Gadget"...& It's listed there.
If you need help with anything, let me know!
