Preferences: Notifications

Me → Preferences → Notifications chooses which pop-up messages you get.

Tell me:

Option	What it does
When I spend L$	A message each time you pay for something.
When I get L$	A message when someone pays you.
When my friends log in or out	A message when a friend comes online or goes offline. In Nearby Chat shows it as a line in nearby chat instead of a pop-up.

Always show and Never show list the pop-ups that have a "Don't show me this again" option. Select one and use the arrow buttons between the lists to move it, for example to bring back a warning you switched off by mistake.

To pause all notifications for a while, use Communicate → Do Not Disturb.
