LiCR,
I enabled Tagging of posts with suggested or ad hoc labels so if when someone creates a new topic, or if a new thread has useful info about certain common themes it will be easy to find topics by category Tag. If you use the webpage front-end to the forum posts you may have already noticed some of the tags we are currently using, depending upon your view (this is Standard View):

The Topic Tags in gray to the right can help you find more related topics. For example, click the Garden tag to provide a list of all the Garden-related topics or the Volcán tag to find Volcano discussions. When creating a new Topic one can choose a Topic Tag at that point, or one can be added later as a conversation evolves. I've added the few you see now. When posting online there is now a Tag option towards the bottom of your compose screen:

Please let me know if you have any questions or suggestions about using this feature.
¡Puro ordenado, Batman!
