I would like to report:
If I set up the site in Italian many parts disappear.

For example, the link for the forum does not appear in the main menu.
I realized there was a forum only thanks  the user Hessa who pointed me to a post for guidelines.
Once I get to the forum, if I keep the setting in Italian, the index of the forum does not appear, the latest  discusons do not appear etc .. I can only browse it by looking for direct links .


Personally, now that know, I can set up the site in English, but if a new user setting up in Italian might think (like me before  understand) that a large part of the site is not working.
I hope it will be useful. 

later  will introduce myself in the appropriate section that I finally found.

Hello
