In Rayman Adventures, I don't know how am I supposed to add friends. The game simply tells me to invite them, but it doesn't tell what do you have to do to add them.
I click on the letter with wings and then on the top-right purple button to add friends. It then redirects me to a Facebook page that shows my friends and tells me to select which ones to invite. I select them, then the site loads for a second and then it sends me back to the mail menu and nothing has changed. What is supposed to happen? Is even anything supposed to happen?
