http://en.wikipedia.org/wiki/Tag_cloud
A tag cloud is a visual depiction of user-generated tags used typically to describe the content of web sites. Tags are usually single words and are typically listed alphabetically, and the importance of a tag is shown with font size or color. Thus both finding a tag by alphabet and by popularity is possible. The tags are hyperlinks that lead to a collection of items that are associated with a tag.
Recently, the ability to tag threads has been added. Adding tags to new threads or existing threads is a helpful feature to make the forum more user friendly.

To add tags, look for the tag box at the bottom of the message box when you start a new thread, or in an existing thread, click the "add tags" link on the bottom of each thread page.

The Tag Cloud can be accessed from the search link drop down on the navbar. Also, tags are displayed in a box near the bottom of each thread page. Clicking on a tag will allow you to view other threads that have the same tag - and which may be related. Clicking on the word 'Tags' in the top of the box will take you to an overview page with a 'tag cloud.'
This cloud allows you to see which tags are the most popular - the larger the word, the more times it has been used on threads within the board. There is also another tag cloud on the advanced search page that shows you the tags that have been searched for (or clicked on) the most.

Note - don't use words for tags that aren't helpful for searching, in other words, don't use the tag "troll" if you think someone is a troll on the thread but it would be OK to tag "troll" in a thread about trolls. (btw - trolls should be reported using the "report post" triangle at the bottom left of the offending post.)

Use commas between tag words and phrases:
In a thread about the Red Bar, tags might be - red bar, restaurant, grayton beach, bar, live music, dining, picolo's

Your help in adding tags will help make the forum better for everyone.
