The other day I ran across a cool extension for BlogEngine.net called Quick Links that replaces certain key words with a link to a site you specify.  I installed it immediately, as I expect most everyone working with BlogEngine.net   did.  I ended up communicating with the author who hosts the CK's Tech Blog about how this extension would be even cooler if it could automatically convert a string of text into a URL.  So after a couple of days he release another new extension that does just that.  Naming it Quicker Links, this tool is absolutely awesome, providing a much needed shortcut for inserting URLs into your blog.  Of course I installed this gem and will be using whenever I post something.
