BTW, i have an off topic question for you, i need to change the name of one of my items, can you help me?
As of recently, you can actually change your items’ names yourself! Just head to the item’s “Edit” tab and you’ll find the item name field about halfway down the page. Keep in mind this will need to be submitted to the review team for approval though.
manuelvega is right – in most cases if you want to include (for example) a CodeCanyon plugin in a ThemeForest theme, you’ll need an Extended License for the plugin and specific permission from the plugin’s author.
There are a few exceptions though. They’re all covered in our licensing FAQ (aaaall the way down the bottom – see the question “Can I purchase an item to use as a small element within a larger project that I plan to sell as stock or a template? For example, could I purchase a button graphic for a theme I plan to sell?”).
As always if you need any more specific help, just contact Envato Support!
Just showing up late to chuck in some links to some specific articles for those who are interested!
