One of the things I wanted to make people aware of is the "Tag Clouds" in the blog and discussion forums. You've probably noticed that when you post or reply to a post at the bottom of the message area there is a tag section. Think of a tag similar to a category or topic. It can be broad or narrow, or sometimes more than one category fits a post. Some tags have a larger font than others. The size of the font indicates the amount of items that have been tagged with that term.
The purpose of these tags is to serve as a quasi index or trail of breadcrumbs for site visitors. If you click on a tag it will take you to all the forum entries or blog entries around that tag. It's just a quick way to access posts on a particular topic.
I would encourge people as they post to tag their posts. You can do this by selecting a tag that already exists by clicking "select tags" or by creating a new tag simply by typing what you want as a tag in the space for tags. The tag will be created.
Thanks,
Ryan
