I am adding more, I started doing this just last weekend actually (bought the hosting with unlimited bandwidth and 2.25G disk space). I am also working a bit on the technical side: changing the welcome email, adding the ref link to the Accounts page. Also trying to change the header and those green graphics on the front page (very ugly). Anywho this is my current project.
Advertisment method: post one game in forums and tell them to try to beat a certain score. That'll make them want to go on other games and check those out, see the ref competition and advertise for me. All that and I just pay $25, just need to find if I should do an item or if I should pay cash...
