Time DOES fly while you're having fun in the beta, but...
You are using approximately ZERO of your subscription months while you explore and test out the beta. Feel free to use it as much as you like!

Keep an eye on progress.fluent-forever.com for updates and information regarding how we will launch subscriptions.
