Saluton! I want to re-do the first few lessons of the La Teorio Nakamura course by making a new account, but I noted that there was a clause in the Conditions of Use that says, "You may only register once and may only create one user profile." Is this enforced? Thank you!

If this site ever gets a FAQ section, the question about retaking the course surely must be among the first ones in that.

You can retake lessons even if you have previously done them. The only issue is that you see your previous answers. Remember that the results are not published anywhere, so any retake is for your own peace of mind. If you still want to retake the course or parts of it, I cannot see any obstacle to creating a new profile for that purpose. But please be a good net citizen and delete that profile after such retake/testrun. There is a link Forigi la konton at the end of the profile settings page.

Thank you! I'm sorry for replying so late. I completely forgot about learning Esperanto for a while! As you mentioned, I want to be able to do it without seeing the answers for the exercises so I can be sure I'm learning it well. I'll make sure to delete it after!
