I have an idea for making wordpress resources(plugins and themes) as more user friendly, I plan to develop a great application, it serve a great support to wordpress users. For ex: If user want to download any plugin for his own purpose, so he is going to search plugin by some keyword. right? I an going to give some advanced filters and options to find the plugin as exact or more relative. So here, I need all wordpress plugins and themes and updates then I can develop this application as soon as possible, Definitely it will useful to our wordpress users. I can download all plugins and themes but I have some question here.
1. To whom I contact to get permission to use wordpress plugins and themes.
2. Do I need to get any other permission to do this service?
