Yes, unfortunately some people take the "Critic" part a little too seriously.  We'll be doing are best not to let that attitude infest our forums for sure.  You'll find an easy to use "Ignore User" link in the header of every post too. After clicking on it, all of that user's posts will be hidden from your view.  I think when the chronic pessimists and complainers get no replies to their posts they'll get the hint!
Welcome to you both ...and spread the word that we're here!
