I found a great site that will let you submit your web site URL and get 365 days of ad space on their site. We can all use the extra advertisement and it's completely free. http://www.hits2u.com/?502032
In response to the question below yes, you do have to get three other people to sign up. If you don't know three people with a web site or at least a blog (active rain for example) I would be quite surprised. This type of free marketing is called viral marketing. Viral marketing, although a form of shotgun advertising (no particular target) is very helpful as it increases Search Engine ranking. The more links to your site and the more hits you get increases your ranking and website exposure. Even though you need to refer three people to get advertising it still won't cost you a dime. E-mail it to three people that could use the ad space or simply post a link like I did here. My electronics website has over 32,000 hits for the month and I only started the site in the last week of December. Viral marketing is a big part of that.
