How to make the show signature checkbox not auto-check

[Lynne]

I don't know of a mod to do that. Did you try a search? Otherwise, I suppose you could find the template and then remove the condition around it that makes it so that option is only shown to admins. Of course, you'll have to test that and see if it works and there aren't other checks in place that would cause the user to get an error or something (so try it on a test site or test style).
