Did J R die and leave you in charge ?
Jim and John still run the show.
When I first came here a few decades ago, we had only a few HTML tools available to us. It was pretty primitive around here. Over the years JimRob and John gave us a good set of tools to make our posts better and make us better contributors to FR. The HTML Sandbox is a fine place to learn how to do the basics and even do things that I've never had to do, such as post arrays.
