Good news; my brother just agreed to post here if I die to let you all know. Don't take that as strictly the only criteria, but if "Rhetro" or something like it comes by and says "David is dead" or something along those lines, you'll have a pretty good idea. I doubt anyone will impersonate me, but if they try, just try to do a voice/video chat. I'll almost always be willing to do that if you ever doubt my identity. Go ahead and assume it if I stop posting, but that'll lock it in.
