Good point. I was thinking that because it's just software, we could restore the old account to its exact prior state. But the attention that accrues to a moderator account would make that impossible. So I guess I'll keep the offer open for three months, after which we can make some other arrangement.
I probably should have picked a different name, but I was swayed by sentimental considerations: it was my email handle at my first job, and, my code tends to be about twice as long as pg's so maybe my username should be too.
Maybe you could give yourself and other admin/mods a different color for your username. Then there can be 2 "dangs" (of course this may need some hacking).
