First of all thanks for this nice plugin, it works like a charm.
I'd to replace the default tag permalink structure by something based on Tag groups. ie. Instead of having "site.com/tag/volkswagen", I'd like to use the tag group to dynamically change the base, to become: "site.com/car/volkswagen"
How can I do this please?
Under Sttings -> Permalinks, there's an option to change the tag base, so I've put %tag-group%.
But how to register this new structure then ?
