Judging by this post: http://themeforest.net/forums/thread/can-i-include-a-plugin-in-my-theme-package/77729 , it’s okay to include existing WP plugins (from wordpess.org) in your themes.
There are few ways in my mind to do this, create a plugins directory with the files (which the user will have to manually copy and activate) or include the files in functions.php
My question is, which is the common way on ThemeForest, judging by technical and legal point of view? (Does ThemeForest has any rules or recommendations on including WP themes?
@debird Yes you can.
