Nightly Tester Tools.
This doesn't help with Conquer Club specificly, but it does have a nice feature. If you have Nightly Tester Tools, you can right-click any add on and force it to install, regardless of compatibility.
This is helpful when someone makes an add on that you really like (ie ConquerTell Notifier) but they stop working on it, it take too longer to updated it to the latest version.
