I'll check the plugin with wordpress 3.0.1.
The next weeks we will provide a new wordpress plugin with some more features, because we have enhanced the background system. THen we have to touch it anyway.
In the next version there is no requirement to send the created pdf files to an email address. It can be configured that the created pdf files are sent to the browser so that the user can download the file directly.
The resulting PDF file will be better than the files which are created currently.
THe new things will be provided the next 2 weeks.
