When the new version of the BB was installed, the programmers/decision makers apparently decided the signature area just used up space, or something. So, not only does it stay hidden, they limited the number of characters. I discovered this when I tried to add my latest cars, and got a message that my preexisting signature was already too long, so the only changes allowed were to reduce the blather. I inquired and was told “hmmm, we’ll look into it”. That was right after the new site went up, so must not be a high priority.
I find amusement when a site dedicated to Alfas tells a paying subscriber “sorry, you’ve had, or have, too many Alfas.”
It is the same logic as when a merchant refuses to accept American Express. It’s like saying “we don’t want to do business with people who have a limitless buying capacity”.
