Very nice crash reporting tool. Unlike Unsanity's Smart CrashReporter it doesn't require the user to install anything and unlike Zonic's Bug Reporter, it doesn't require interaction of the user with Mail (and on top of that it's free).

The only downside is that, depending on your setup, sending mail directly via the SMTP server of your email address may not work. Fortunately, the source code is included and is written in such a way that it is quite easy to use instead the NSMailDelivery class from Message.framework. It would be nice to have this as a proper option (maybe together with the possibility of calling a cgi script instead), rather than having to tweak the source code...
