Since 37Signals introduced their single sign-on solution aka Launchpad, it takes a little more effort to create a Fluidyapplication for Campfire, Basecamp, and all the rest of the tools since authentication happens on one site (launchpad.37signals.com) and your application is on another site (eg. bacon.campfirenow.com). But the fix is easy:

1. Create your Fluid App as normal
2. Go to Preferences > Advanced
3. Add *launchpad.37signals.com* to the list of allowed sites

For extra credit, you can add the related URL paths for any of the other 37signals webapps so you can use the menubar you get on their sites when you’ve authenticated with launchpad.
