User history doesn't update after 20 records

Hello,

I would like to effectively monitor the activity of my users using the EasyDiscuss backend component. I see that under 'Users' there is an activity log - very helpful. However, I notice that once the activity log reaches 20, activity is no longer logged. So I only have data for the first 20 instances of activity for any one user.. not ideal!

Is there a way of changing this to ensure all activity is monitored; or at the very least, the most recent?

Thanks!
