The account I'm now using, dang, was used briefly in 2010 by someone who didn't leave an email address. I feel bad for not being able to ask them if they still want it, so I'm considering this an indefinite loan. If you're the original owner, please email me and I'll give it back to you. The reason I want the name dang is that (a) it's a version of my real name and (b) it's something you say when you make a mistake.
Second, very minor, but I need to leave this discussion for a bit while I bike to a different location. After that, I'll be in the thread... but I'm not giving up my bike ride for this :)
(Edit: it turned out from old logs that someone had made a bunch of different accounts with names like "dang" all at once, so in retrospect I was reclaiming a dormant sockpuppet!)
