find user without sig (sql query+)

[Sculli]

This is certainly very curious. The query looks like it should work, yet it doesn't, meaning it returns less than the expected number of results.

Here is an extension of this mod request: A mod that would allow the admin to SET the signature of all those who have not set one themselves. That would be most awesome.

P.S.: Still experimenting with queries to try and get to the bottom of why this doesn't work properly.
