Just another idea for gamification. We could implement also a feature in Zurmo that tracks the completeness of a record (Account/Opprtunity). The more key fields are populated by the end-user the better it is. And could win more game points! We could display also a progress bar for that Opportunity ("You have completed Opportunity X 65%").
Subsequently we can help the user in completing its records by giving tips how to complete. For example: "Do you know you can reach 75% of Opportunity X just by adding a meeting to this opportunity?". More points to gain this way...
Just some idea I had last night....
