Loading an old revision

Sometimes while you are working on your profile you’ll want to test a particular revision that you created in the past with gMT. To do so, load the desired revision on the editor and then click on the ‘preview current’ link on top of the editor. To load an older revision, go to the ‘History’ tab, select the desired revision and then press ‘Load selected’.
This is useful to go back to previous states of your profile or to back changes that that didn’t work as you expected.
