Working with Tag Clouds
Tag clouds are a bit of a work-in-progress here, but the idea is all the tags you use on your site can be displayed in a way in which (a) often-used tags are bigger, and (b) tags are linked to a page that displays the particular news, events, etc. in your groups that use them.
Below is a sample tag cloud from this support site. Note: active links below don’t work properly for now. This is to display the size differences as explained.
