From what I know it's a two-step process:

(1) the boss boots all members, but himself can't leave. This is because chess.com settings require at least 1 admin or superadmin to still remain in the group.

(2) call kohai. Only staff can delete a group out of existence.

Just make someone else the super admin, make yourself a member, then quit the group. Make it the new guys problem. 

That's the newfangled way of course ..

Is that how I ended up as the only Super in so many groups?  I guess I'm the "new guy," eh? 

Also, if the group has EVER played ANY team matches or Vote Games, then it can NOT be deleted because doing so would mess up all the records within all the other groups that they had played.

If only this group + group idea had been implemented.

Would there be a provision for hostile takeovers under such a scheme?

You've seen group-hysteria post #15? And who could forget stop-thief---they-stole-our-name?
