This plugin will create a tag cloud for a specific author. This will allow a visitor on your site to drill deep down into an author’s specific content.
It uses all of the same parameters as wp_tag_cloud(), but adds an additional one for the author_id. When the author_id is passed an integer of a published author that has tagged his or her posts, a tag cloud will be generated.
It will also create a new permalink structure on your site of
www.yoursite.com/author/author-slug/tag/tag-slug
***Note: that you must be using any custom permalink structure for this plugin to function. Also, custom taxonomies is currently not functioning with this version, please look forward for this in a later version.

Author Tag Cloud

Creates a template tag to create an author specific tag cloud and creates a new permalink structure to drill down into content by author and tag.

The plugin integrates with the standard WordPress tag cloud, but allows tags to be excluded and easy control of other settings such as min and max font sizes, the sort order and number of tags to include.
This plugin is multisite compatible.
This plugin supports language translations. If you want to translate this plugin please sent the .po and .mo files to development.translations@azurecurve.co.uk for inclusion in the next version (full credit will be given). The .pot fie is in the languages folder of the plugin and can also be downloaded from the plugin page on http://development.azurecurve.co.uk.

I love Software which intelligently uses already available resources - in this case, the WordPress Tag-Cloud function, with all the options provided by the function but not settable in the standard widget. Sure there are other tag cloud plugins out there, but in comparison to this one they are sure going to bloat your frontend code!

A great boon for MultiSite users is that this plugin offers global settings in the network admin area. Then each site can either opt to use those, or set its own. Now that's really sweet!

Finally, the support from Ian, the author, has been superb - fixes done within hours even at the weekend! For my part I pronounce the new version "bug free" and was glad to help polish a great product.

Thanks Ian!
