original signature file when you switch between the various formats for
your outgoing messages - usually not very satisfactorily.
The easiest way to send your signature to somebody else would be to
attach the file to a message you send to that person. Then they can save
the attachment in their signature folder (see above) and it should show
up in Menu: Insert/Signature>, possibly under More...
