The Tag cloud module displays all the words you have used to tag your photos and blog posts, providing a visual depiction of the content of your network. The words float about the module, and their size represents how often they have been used (larger words have been used as a tag more often than smaller words). All words are hyperlinked so if you click on the word you will see search results associated with the tag.
Settings
Number of tags to display: choose the number of tags the cloud will consist of.
Tag cloud height: define the size of the module.
Show tags for: choose the source of the tags to be included in the tag cloud – Everything (including all networks, users, and content), Content, or more specific types of content (e.g. Blog posts, photos, etc.).

Allow replication – allow other users to replicate this module and display their own tag cloud on their network.

Additional notes on the Tag cloud module:
- clicking on a tag searches for content within the current network matching that tag.
- the module can only be used to display tags of the network that it is placed upon.
- the module does not display your 'user tags' like the moodcloud
