Questions about the bonus skills
I was just wondering what is going on with the bonus skills: Usually they are unlocked in the lingot store after you pass the first checkpoint. When I passed it nothing happened on the Esperanto tree, but when I went to the lingot store on my Spanish tree, under the category of bonus skills, it said that there three open slots (even though I bought all three bonus skills), and it showed me that I can buy flirting and Esperanto culture.
I heard that bonus skills are not available yet but will be soon. Esperanto is still in beta and I believe that contributors are working hard (especially because the amount of reports is probably enormous). Be patient and learn other skills in the mean time.
