Ability to link to your own (non-PB) blog feed's latest entry?

[Casey]

I think the forum had this ability in the past (or I've seen other forums that could), but for blogs that aren't hosted on the PB (Blogger, WordPress, etc.), would it be possible to have a link to the latest blog post in the header area of posts where it currently says "Blog Entries:"? Or is there some kind of code to do something similar in our signatures? Just an idea!
