Licences of Yii Extensions

Hi there,

I’m currently planning a new Yii based application and want to publish the result under some open source licence. After exploring the extension library I start to wonder under which licence they are published. Couldn’t find any notes or author, copy right holder, licence in most of the extensions I consider to use for my project.

Does anyone know under which licence the extensions are published? I mean do the uploader agree to some licence by uploading it?

If no how would you suggest shall I get clearance for all the code I’d like to use?

Thanks!

On the extension page… when you select an extension… check the right column under License:
