Let's get list members who uses LedgerSMB or who have consulting clients using it to write up brief summaries and forward them (to you, if that makes it easier). They can be anonymous, but in any case should include size of company (revenues, number of users) and what motivated them to choose LedgerSMB. Then you can include whatever is appropriate on the testimonials page, if the sender is ok with publicizing.
This information is vital to marketing LedgerSMB.
