I have done the "I agree" thing but mostly because something drew me in enough to want to say something but I was scared to say more than that on a possibly controversial topic.
BTW, I've lurked here for around 4-5 years, joined in '11, and have only recently been sticking my toes in the water posting. It's our third year homeschooling (first with more than one child) and I'm just now feeling I may have the tiniest bit of help to offer. The search function helped with many decisions along the way.
