Jerry from the looks of things you have been playing "catch up". That's why the information is here. In fact you would be a perfect candidate to solicit some information from that would encourage some additional articles from anyone here. For example, (for those that don't know) you and your wife have a serious interest in getting into the tile installation business and your wife has already completed several nice jobs in your absence. You haven't hesitated to ask questions and clear up confusion at times, that's a good thing. The ADMIN here is always looking for someone to write articles that are beneficial to the pro flooring installer. So........why don't you and your wife get together a list of things you would like to know more about ( relating to tile and flooring topics) and that you guys think would be beneficial to someone in your positions and let us know. I'm sure there are many pros here that would be happy to take the time to write some articles to add to our collection here.
