Guys you are right, I have to apologise for my post.
Let me know you the reasons because I'm asking here:
- in Italy there is not any specific support for Kunena;
- there is a Joomla.it community but... impossible to find somebody there about Kunena;
- there is Kunena.org, but after login for me is impossible to read or write.
This is because I have tried here.
Thank you for your link.
