What are tags? So what are tags? Tags are keywords. Tags are useful because they allow you to collect all the threads with a certain tag/keyword into one place (for instance the CookingBites Recipe Challenge tag). Tags/keywords acts as a filter across the entire site, so no matter where a thread is on the site if it has a particular tag it will show in the list when you search for that tag (under the Search Forums, then Search Tags option) or just click on the tag itself when you see it in a thread. So try it - click on this CookingBites Recipe Challenge tag now and see what you get. You can add tags to any thread you come across, to a maximum of 4 tags per member or 7 tags per thread. (So one member could add 3 tags and another add 2, and 3rd member would only be able to add 2 more tags.) If you did, you will see that you got something like this (click on the picture for a larger view)... The list will change because the challenge changes every 10-15 days, but you get the idea. So tags are another way of searching to find what you are looking for and on a cooking forum, this means that you can much more easily search for a recipe with a particular ingredient in it because it is often possible that a recipe can go into more than one location within the site.
