Then how will sockpuppet, you in all but name, leave? This is a classic invariant problem, man. Addendum: Though, since we're all Marks, technically there should always be someone left.
I'll have to log back in with my main account to kick the sockpuppet, and then log the puppet back in to kick my main, but then, using my main, log in to kick the puppet, and but... Uh oh. I see what you mean. But this is my life, now. The rules are rules. Some apportionment of me will be stuck in the Jit.Si forever next time I log on. Wait! What if I make a third account?? The third account logs back in for the sockpuppet, to kick it, and then my main account comes back in, right? Then the sockpuppet, AND the third account, then p.s. This collective, us Marks, we go by marcUS, the plural, hip & cool, U.S.-based conjugation. The rules are rules.
