Looking for a add-on that will let a user login with twitch and create an account that will work on the forums. It would also need to see if the user is Subscribed and/or following a specific channel(s) and would add them to a group (possibly interact with the user upgrades?).
Here is some of the info I have found that could help
Feel free to send me a message if you need any other info or questions!
I am sure there are a lot of people of there that would love this also
