We really need some tutorials in Skript docs. Following topics would be most important:

• if-else blocks explained
• Events handling
• Custom Commands & Command Event
• Sections/Structures Explained
• Loops Explained
• Variables Explained
• Declaring new functions, how returns work
• Chat formatting, especially now with advanced JSON stuff
• Visual effects tutorial, as they can be quite hard no matter how Skript does them

... and probably some more things.

So, anyone interested? Just copying some existing tutorials with authors permission would be good enough. Writing new tutorials wouldn't be bad either, if someone has time for that ;)
