Is there a way to remove the signature from PMs?
Uncheck the include signature box?
Well yeah I know that... Just wondering if there was an option somewhere or something. (Seeing as how it doesn't seem to have it's own template right? It just uses the Postbit/Classic template?)
I think you need to edit private_send templates.
If you set the value to "0", no matter if it is checked or not, I think the pm will not contain the signature.
