I have a problem with the members signatures, If a member ticks don't show my signature in their profile I assume it shouldn't show but it does why is this?

Did they untick it in the post? e.g. when you preview a post. I think for the first time after disabling your signature in your profile, you must untick it when you go to post something and then after that it will automatically stop posting signatures in your post.

Ok thank you I'll check
