I was wondering if you can publish your iWeb blog to another server location and not just a .mac account. I get free web space from my school and don't feel like shelling out the extra money.
You need to Publish To A Folder. This will stick the site in a folder wherever you choose. Just put the contents of that folder in your web space, and it should work .
You can publish your webpage as a folder, like others have suggested, but I don't think it will have most of the interactive capabilities of a blog, such as the ability to leave comments.
