We use tags to make it easier to find posts on certain topics. This takes two things:
We allow anyone to add any tag to a post (point #1). We also allow anyone to upvote or downvote the tags on a post.
If a tag on a post falls to zero karma, it is removed from the post (point #2).
If a tag gains additional karma, its post will be seen as more relevant for that tag, and will move up the list of posts on the tag page.
When in doubt, please err on the side of adding a tag! Other users can downvote it if they don’t think it should be attached, and the more people suggest tags in the first place, the better-organized the Forum will be.
The Community tag covers posts about the EA community, as well as applying EA in one's personal life. The tag also applies to posts about the Forum itself, since this is a community space.
Existential Risk is a very broad tag, and can apply to any post which discusses risks to human civilization or the human species.
The Movement Strategy tag covers posts about improving the prospects of the EA movement in ways that don't directly relate to improving our reasoning; for example, through growth, media relations, or internal coordination.
Cause Prioritization: Finding the most important causes to work on and comparing interventions across different areas, so that we can do as much good as possible with the resources available to us.
The Coronavirus tag can cover posts about any aspect of the pandemic (biological, social, economic, etc.)
The Career Choice tag is used for posts about finding a high-impact career, whether that means choosing between several fields or applying successfully to jobs within one's chosen field.

Use the Org Update tag for posts where EA-aligned organizations share their recent progress and other news.
Wild Animal Welfare posts discuss ideas and interventions related to improving the welfare of wild animals. For discussion of animals that are farmed by humans, see the Farmed Animal Welfare tag.

The Policy Change tag is very broad, covering any post about improving government policy (in developing and developed countries alike).
The Global Health and Development tag can cover any post about improving public health, reducing poverty, or increasing economic growth; most of these posts will discuss the developing world, but this isn't strictly necessary.
The AI Alignment tag is used for posts that discuss aligning AI systems with human interests, and for meta-discussion about whether this goal is worthwhile, achievable, etc.
The Longtermism (Philosophy) tag is for posts about philosophical matters relevant to longtermism, meaning, roughly, "an ethical view that is particularly concerned with ensuring long-run outcomes go well" (MacAskill). Longtermism is a relatively new idea, and people in the EA movement currently work on a wide range of open questions related to different facets of longtermism.
EA Funding posts discuss EA funding networks, the availability of funds for different cause areas, grantmaking strategy, etc.
Not meant for posts that discuss specific funding decisions (for that, use the "Donation Writeup" tag).
The Moral Philosophy tag is very wide-ranging, and can be used alongside more specific tags like Longtermism (Philosophy).
The Climate Change tag can be used for posts about any aspect of the topic (research, funding, prioritization, and so on).
EA Lifestyle posts discuss ways to integrate effective altruism with the rest of one's life. Topics include mental health, childcare, personal finance, and more.
