Yes, I chose to show at least some respect for the wishes of the Joomla developers, even though I strongly disagree with them. This is not only because I'm an all round Mr nice guy

but also because I would like to make nBill available for other CMSs or even standalone in future, so I don't want to be too tied to Joomla's API anyway.
Fair enough, would love to see it back as an option though :-)
