More Tag Clouds, Multiple Tags per Group and more

The free Tag Groups plugin gives you all you need to organize your tags in groups and to display them on your front end. If you like to extend the functionalities to posts (replace the tag box with one where tags are available in groups) or assign the same tag to many groups, you should take a look at the premium plugin.
