You have to buy your own domain and then have it point at your blogger account. about how to do it. I remember it being pretty easy and trouble free! I still pay for the domain through my favourite web host provider.
Cool, Wordpress is a very strong platform. Some things I'd do to change:
1. Move the download link to the top of the right column. Even above the search box. Most people who come to your site did so through search, so 95% of them will be wanting the download link. 2. In the download list, make sure the RPG Core rules are right at the top, in bold, perhaps using the cover picture as a link. 3. I'd remove the bullet point marks by the site of the links in the list, indenting is enough. You might want to get rid of the underline too - there's no need for it. 4. Your header needs to be more impressive and should scream Sci Fi. At the moment, to new visitors the artifact picture just looks like a colured blob. You have COPIOUS quantities of superb art, pick your favourites and photoshop them together. 5. I'd put a tag line under the title: The Article - A Free Science Fiction RPG.
Great Onix! I'd stick some text with (or over using a graphics package) the cover image on the right with a 'Click here to download'. This follows a 'don't make me think' principle of web design.
