About

Every question asked on Stack Exchange can have up to five tags that categorize the question.

Use this tag for questions about existing tags. For discussions on what a meta-tag is or if an existing / proposed tag is meta - consider using meta - especially on meta - we might love disgussing if meta-tag on meta is indeed a meta-meta-tag.

Meta sites have tags that need to be present in the question, which are bug, support, discussion and feature-request; there are also tags that can be added only from moderators, such as faq, featured, and status-declined, which are shown with a red background.

For more information see the section on tagging in the FAQ.
