Once posting is unlocked, you can share a post of up to 500 characters from the Composer. Posts can also include tags — small clickable chips attached to your post that reference something specific, like an achievement you unlocked, a game result, a multiplayer win, your current rank, your streak, a completed mission, a Mall item, an Artifact, or even another player by mention.
Tags aren't just decoration — tapping one takes the viewer straight to whatever it references (like a game, if the tag has a link to one), which makes it easy to show off a specific achievement or result instead of just describing it in text.
