When you're running a service like Mixer, you're bound to encounter problems from time to time. Not everyone is affected, but it seems that enough has been recently to prompt the team to offer out some freebies to the community.
The only conditions are that you're level 10 on Mixer and that you login at least once on April 14 or April 15. Within a week you should see one free subscription added to your account which you can use to subscribe to any of your favorite streamers.
Fortunately, there's plenty of reasons to log in to Mixer this weekend. My personal favorite is the Halo World Championship finals going down in Seattle, with a prize fund of a cool $1 million. Catch all the action on the Halo Mixer Channel.
