Hi tennistutor, I moved it to the right location because in General Messages we don't allow discussions about personal or commercial websites.
3.8. If you have a tennis blog/site and wish to post your articles here to open a discussion, go to the Fan Blogs section.
But it's allowed to link to your page in your signature or to link to it if it serves the discussion (like for example when somebody in the amateur tennis forums asks for information about string tensions which is described in detail on your page). Just don't do it excessively, thanks!
