Setting them is easy, yet managing the landmarks (LMs) is difficult. The names in your inventory can be confusing, and you will soon have a pile of LMs.

To set a LM, go to the place you wish to appear when you teleport (be on the ground or you'll fall when you teleport there next time, Mr. Funny-man), then to the "World" menu and select "Create Landmark Here."

These new landmarks will appear in your inventory and, with a double-click, they'll appear on the screen, ready for you to click "teleport" and appear instantly in the new location.

Scavenger Hunt Bonus: 50L to the first student to create a landmark somwhere other than Orientation Island and sent it to Ignatius Onomatopoeia (use your search tool --> People tab to find me, if I am not already on your friends' list).
