Totally confused Quilter

I need some serious help. Well, I do need help in lots and lots of areas but, for the sake of this discussion, perhaps I should narrow down the field. I need help at this moment with this computer stuff. Not narrow enough? O.K., I need help with this "sharing" thingie I keep seeing on things like "Facebook," "Google," "Google+," you name it....oops I suppose that just un-narrowed the field. Hellllllp. I am told, "Dianne, why don't you just hit the sharing thingie so you can post your blog on Facebook? Or, why don't you "share" on Twitter? Or, "share" some of your creations on.....WHATEVER!!! I DON'T KNOW TO DO THIS SH....um, STUFF!!!
