Bonus XP Points
Bonus XP point allocations are quite significant and can greatly affect the speed at which a user increases their overall XP tally and level up within Zurmo. New badges and category level ups are quite common when a user first begins to use the system and the bonus XP points that they generate provide a positive early experience to the system.
Over time it will become progressively more difficult to achieve level ups in a categories you are already strong in, the same is true of progressive badges that have been upgraded multiple times.
But this provides an incentive for users involved in “the game” rewarding them for strengthening categories they may otherwise neglect and encouraging exploration of the system with new badges.
