Once you click on the Notifications & Questions tab, you see a window as shown below:
Figure 1: Notifications & Questions Tab
On this tab you can set, which notifications should be shown or not. The options available are quite self-explaining. Simply let the ones you would like to have marked. Others you do not necessarily need can be deactivated.
Please Note:
If you had a Warning popup already and marked it to not be shown again, but later realize that it would be good to have the popup (i.e. for not accidently deleting the EventLog), you can simply reactivate it here.
