Me neither but I know of some who access their site and read their stuff as opposition research without ever registering.
Here's how they do it:
Just click on bugmenot.com and read their faq. You can get access to virtually any news website that requires registration without ever actually doing so. For all I know you can get on FreeRepublic using the same scheme (just kidding but I can't actually check that out.) Just put their little icon in you links bar and whenever you need a username and password just click on the link and a window will pop up with the info you need. Just use it once and you will be able to log on forever to that site.
Sounds almost illegal. May be. But it works.
Yes they do list false FR accounts that can be used to get onto FR without having an account!
