Hi,
We are updating the recommend a lesson feature on the site. While we are updating it you will notice lessons we have published appearing in the songs you can vote for again. This will be temporary while we update our database. So if you notice this area is a little out of whack we are working on it today.
Look forward to an easier to use streamlined system that also prevents duplicates from appearing when someone tries to add something new that is already on the site.
Thanks,
Mike
