Justin, to subscribe to the WF blog via an RSS reader, use the following URL:
http://www.websiteforge.com/blog.html?m17:feed=rss2
If you are going to have your own blog on the WebsiteForge engine, it will have a subscription URL too. It will look like:
http://www.yoursite.com/XX.html?mYY:feed=rss2
where XX is the number of your page where the blog is located, and YY is the number of the blog module.

In few days we are going to have some upgrades, one of them will allow your browser to automatically find out that RSS is available on the blog page and to suggest visitors to subscribe. Usually browsers display an RSS icon in the address bar which creates an RSS subscription when clicked.
