Hello friends, i am from Italy.
I speak a little english and I hope to grow with you 
I have a doubt : is there a section in the forum to find useful Web resources (such as sprites , sound effects, music , etc … ) ?
Thanks,
J
Welcome!
GDevelop comes with various sprites to start with a good sketch fastly, but I have seen some other graphics/musics sharing here, for example this great contribution from Eric Matyas: [url]Sharing my Music and Sound Effects - Over 1500 Tracks]
Anyway, there is not a specific section to share resources
