One other little goodie I forgot to mention. I still had a reason to want to disable the blog from automatically adding the feed discovery link, my reason is because I want that link on all the pages in my site not just the blog, from anywhere in the site I want users to easily be able to subscribe to the blog. So I wanted a way to be able to add the link myself in layout.master to accomplish this. I did add a new setting in the blog to turn off the automatic adding of the discovery link, then I created a new control that I could add to layout.master and it would handle adding that guid to the link for me. So in the new release you will be able to use this as well if you like, you can it to the head section in layout.master like this:
<portal:FeedDiscoveryLink id="fd1" runat="server" FeedUrl="http://www.mojoportal.com/blog19rss.aspx" FeedTitle="mojoPortal Change Blog" />
I just hard code my blog feedurl there and the control will append the query string with the guid when it renders. There is also a property on the control if one did not want to append the query string with the guid one could add this property on the control:
<portal:FeedDiscoveryLink id="fd1" runat="server" UseRedirectBypassToken="false" FeedUrl="http://www.mojoportal.com/blog19rss.aspx" FeedTitle="mojoPortal Change Blog" />
Best,
