Ha ha, I never rated a topic either and I have been here longer than you. I have rated posts in a thread though, that is pretty easy. Just click the little '"+" plus sign in the top right corner of the post . Or the "-" minus sign if you want to negatory it.
Actually the rate topic option is right above the rate post plus and minus option. Just choose a star level you want to apply and click it. Hovering over the word "rate topic " and then moving your mouse pointer right will reveal the stars.
I meant Rate a post actually. It was all new to me when I started this topic...yes the little + and -, I didn't know they were here it is all new to me from February 2012. Oh and yes there is Rate a topic as well wow this is all new to me. Tell me are there new glasses I was supposed to buy at the gluten free mall or it is just me
