How do I remove the standard cover pages from the FaxFinder Client so they don't show up in Send Fax Cover Page Style Drop Down List?

You must rename, move or delete the cover page templates in two places: your application data directory, and the Installation Directory.
For Example to permanently delete the BoldComplete Cover Page Template:
Delete it from your application data directory (i.e. C:\Documents and Settings\xxx\Application Data\FaxFinder Client Software\Cover Pages\BoldComplete.cpg where xxx is the user in question).
And Delete it from your installation directory (C:\Program Files\Multi-Tech Systems\FaxFinder Client Software\CoverPages\BoldComplete.cpg)

This is for the FaxFinder Client.
