Was read the codec and knowing WordPress have some code standards of their themes. And all guys can submit their themes at WordPress’ theme directory, but with long trac/theme-review process to ensure themes meet their standards. And some of Themeforest’s themes I saw, those didn’t meet the WordPress standards. I’m really confused about this stuff.
And, how if I submit my theme to the directory and I sell the premium here? Is it allowed?
Why would anyone buy the theme here if you offer it for free in wp directory?
I think you can if you sell “non exclusively” on themeforest.
