Since it's very easy to accidentally click the "Mute" button, you can mute Earn2Life mainframe, so it stops delivering landmarks. These short illustrated instructions will help you to unmute the E2L landmark storage.

Step 1

Open the "View" menu and click the "Mute list" item

Step 2

In the "Muted Residents & Objects" locate "Earn2Life.com" object and/or "Glazhan Gassner" resident and click to highlight it

Step 3

Click on the "Unmute" button to remove these items from the muted objects list. After you have finished this you will receive all necessary landmarks from this point on.
