support Mixcloud, Youtube, MEGA,
which extension supports mixcloud, youtube, soundcloud, vimeo, mega, and other cloud storage sites
wpForo Embeds addon is designed to embed 3rd party videos, audios and widgets. It supports mixcloud, youtube, soundcloud, vimeo... But it doesn't "mega".
in a future?
I don't even know what is MEGA, we have no any plans for this.
