In early of 1996, I have developed a homepage, which I dedicated to a kind of music I really like. The homepage is hosted on Geocities(home of longest URLs' homepage repository) free hosting service at that time. It is almost impossible for anybody to visit my site by accident because of long URL. I tried to let everybody know existence of my homepage, send emails, sign guestbooks, join forums, but I forgot( or I did not know that we have to submit our URL to) search engines. The homepage got very few visitors, until I gave up and just let it be. And now, for your information, homepage still exist, but I have already forgot password. I do not know how many visitors it got per day now because web counter service is also missing.
