WC might not be the answer.
Magnus Carlsen on Chess.com!

I mean, not just GM, thats still a massive accomplishment, but it should indeed be noted if he is the Water Closet - er, World Champion.

For those who were here a few years ago, Chess.com arranged a vote chess match where it was all of chess.com against Carlsen. It was even done via a live broadcast, members here could see Carlsen, members of chess.com staff were in the same room as Carlsen.
Chess.com set the account up for him so he could log into the site to make his vote chess moves.
His verified account will show if he's logged into the site since then and his games history will show if he's played on the site since the vote chess game.
We've all seen them - the titled players with an NM, CM, FM, IM, or GM next to their names. It is not uncommon to encounter a titled player online, and, as of now, the highest-ranking player is GM Hikaru. But what would happen if Magnus Carlsen, the reigning World Champion, found the time to join chess.com? What would be next to his name? Surely not only GM - World Champion status should be denoted by something greater. Would it perhaps be a WC next to his name?
