A new rank with 4,000 activity and 10,000 merits would be nice to achieve.
That's only theymos and JayJuanGee for now. A new Rank has been discussed several times (and my suggestion is "Legend"), and I kinda expected it to happen when at least 100 users qualify for the new Rank already. I don't expect theymos to create a new Rank that almost exclusively applies to him.
I'll repeat my suggestion:
I'd say just "Legend" sounds good. Or maybe just add a bold font to the current Legendary rank.
-I vote for the name Legend. It's simple, and makes Legendary look a bit like "Legend-ish", while Legend sounds like "the real thing".
Since this was years ago, by now maybe we need a few more ranks: 2000 Merit/Activity, 4000 and 8000. That's going to take a while.
Let's face it: I don't expect it to happen.
