Isn't there a way to open a box for "other user"?

This, in fact, *is* the correct answer. That it's enabled is bad.
1. Security. Having the username, which someone being nasty wants to
break into, but doesn't know it, this is just that much easier.
2. You have over 100 users. That's annoying to scroll through. Certainly,
each user *ought* to know their own username, and it's faster to
type it in, than scroll down 5 or so names at a time through 100+.
3. See 1.
