Open source your manuals
From NMR Wiki
If manuals for your commercial system do not contain sensitive unprotected IP - publish them as open source material on a NMR Wiki.
Your clients will appreciate it as wiki manuals can be readily improved and more easily customized for consumers.
Benefit from visits by a growing number of readers of NMR Wiki (~200 NMR spectroscopists daily as of Feb 2009)
Open sourcing your manuals will allow more of your potential clients learn about your well supported products.
