The plugin is great and unique for those poor non-ISO speakers&blogers who can't convert their silly language files into PDF using fpdf library.
This plugin works for us. The only bad thing about it is - it does not have the Setting option page when installed in 2.7.1 WP, so we can't change the default mail-text for example (well, actually, just this)...
So my question is - Stefan! are you going to update the PDF24 till 2.7.1. soon :) or the great plugin is not supported any more? :(
