Edit / Templates / PrivSignature
This is the default template for your signature to PMs, it is put automatically on the end of all messages. It cannot contain macros (there is no need for them). You can define different signature for each newsgroup group with /Edit/Group/Edit/Template, but you have to give them different names using /Edit/Templates/Misc. See also: internal Editor
