Hi @Alessandrafranza1992 and welcome to our community! 
I’m sorry if you haven’t found tasks recently, we know it’s sometimes not easy to find tasks, but in general, the availability of tasks actually varies from time to time 
However, I recommend that you keep checking the homepage, and following these instructions to sign up to receive email notifications when tasks are available in your language pairs, this should help to increase the chance to find tasks 
Hope you can catch your first task soon!
