I found your site by accident and was very interested that you offer practical solutions to problems that you may run into. I have never seen a frame calculator. Thank you very much for that. No other site that I have been to offers that! It's like they want you to guess. So happy to have found you. I saved you on my desktop so that I will NOT lose you. Read just a few of your offers to problems and am so fascinated. Keep up the good work for returnees and beginners alike!!!
