This gets us into some real nitpicky arguments. Suppose you customarily put “Erasmus” at the end of your posts. Do you want me telling you you can’t do that? Do I want to spend time enforcing such a rule? And yes, I know we’ve had a few arguments along those lines in the past. I’d just as soon not go there again.
Incidentally, it occurred to me I was hasty in shutting off autosigs for guests without notice, in case somebody had something they wanted to save. So they’ve been (or soon will be) restored. Once we get squared away on what we’re going to do, we’ll post an announcement.
