So are you saying that these experiments are changing my signature back? If they are, how do I get around them?
@AWOL I still struggle to understand when 'they' will know it is right and how we will find out so that we can just make our changes once. No response from the webmaster, btw.
Maybe you should simply remove the feature if it that problematic.
However, signatures aside, right now it is not possible to set any profile information.
