Re: need help on mental math
I wonder do in that thread we need to actually take only 10 seconds?
Actually I never watch Star Wars and not interested in it anyway, but I choose a Yoda card as my avatar in honor of our great friend bobbym who has passed away.
May his adventurous soul rest in peace at heaven.
