Tag clouds for specific content and specific display locations
Using Jamroom
fyi, what Michael says above would return tags for all that profile's blogs. You could expand the search to specific blogs (or other items), eg. -
{jrTags_cloud profile_id=$_profile_id search="tag_module = jrBlog" search2="_item_id = $item._item_id"}
The $item._item_id variable would be available on the item list and detail pages.
