We use Excel VBA macros in many of our shared workbooks (numbering in the
thousands). When users have macro security set to High, our macros do not
run because they are not signed. This is a serious problem, especially with
the users. While we have a utility to self certify our macros
(SELFCERT.EXE), it does not help unless all users have us in a list of
trusted sources. We need a way to create and maintain this list of trusted
sources. Any thoughts? Can we do this without a rootCA or purchasing
certificates from say...verisign?


Thanks!
