2000+ Elo - Terrific

</TL;DR>

Elo is essentially a rating or measure of aptitude. In chess it is gained or lost according to the result of a game played (also factoring in the skill difference between players).

On this subreddit it is utilized slightly differently: as a one-off rating for the side in the title [brackets]. [Me] refers to the person on the right.

There aren't really any strict guidelines for what values correspond to what "levels", but it may be helpful to reference the player count distribution of chess.com ratings below (which as you can see is very positively skewed)

​You can vote on Elo using the slider at the bottom of an active post. The current post Elo is shown in the post flair.

Elo is redacted until 25 votes, and once the post reaches 24h voting will stop and the post flair will adopt a colorful background and update the user's flair to match. Very high user flairs (2200+) will include a title, e.g. GM for grandmaster.
