When Will Plex Have a Channel for a Particular Website?

Since the individual volunteers who write Plex channel plugins do not control or have any influence over the websites that provide online content, they also do not have the ability to predict the future design choices of a website whose content is currently unavailable.  When and if changes to a currently problematic site are made, and if those future changes allow for stable and continued access to their online content, then you will be more likely see Plex volunteers willing to create and support a channel for that website.
