Presumably, you have arrived at this site because of some content or rumor of content of interest to you. It is unlikely you are here primarily because you found the features or organization of this site especially interesting. You are here to learn something hopefully and not to just be impressed by some gymnastics of presentation. Problems of content on the World-Wide Web are becoming critical. The Web is littered with sites that offer content copied from other sites.
Repetition is rampant.
Just do a search and you will often find dozens of sites reproducing the same information. At this site, you will find all original content. I ask anyone interested in the content here not to make copies of it on other sites. Of course, proper links into this site are always welcomed and encouraged. Though I cannot police and absolutely prevent others from copying my content, I will take action against any abuses that I find or that are reported to me.
