(From finsch.jamika@yahoo.com) Good evening, I was just on your site and filled out your contact form. The feedback page on your site sends you messages like this to your email account which is why you're reading through my message right now correct? This is half the battle with any type of advertising, getting people to actually READ your advertisement and this is exactly what you're doing now! If you have an ad message you would like to blast out to millions of websites via their contact forms in the U.S. or to any country worldwide let me know, I can even focus on particular niches and my prices are very reasonable.
