The tag policy is supposed to serve as a guideline for anyone who wants to post on this website. The policy implies what topics are supposed to be discussed here. If used correctly, you should be able to subscribe (with rss) to the tags that interest you – say if you’re a member of (or just want to follow) the finnish translation team, you might want to subscribe to the tags “fi” and “release”.

request all requests (meaning you’re asking someone in the WP Polyglots team to do something)
announcement any announcements from the polyglots or core team regarding rosetta, glotpress, infrastructure, etc.
release posts about (imminent) new releases of WordPress (should be used with care!)
core posts about WP core, either from core developers (such as string freeze) or questions surrounding core (such as questions with strings)
infrastructure posts about this website (informational, questions, notifications about changes, etc.)
suggestion improvements for this website (suggestions for glotpress belong at trac.glotpress.org)
[language tags] posts about specific locales should be tagged with the corresponding language tag, e.g. “fi” for finnish and “nl_NL” for dutch
