I believe we have had our permission removed to do this. I noticed the other day as the forum is meant to reference an image I had saved and it no longer works so went to change it and can’t. In the forum software help thread I’ve mentioned this but had no reply from @proffrink yet.
*** @BigAl to appease my need to correct the wrong, you do have a section in your profile to turn off displaying signatures. I know it means that others can see your sig but if it's irking your tism, at least you won't see it any more
