If a user tries to subscribe to new follow-up comments on a post where they've already subscribed, this message pops up: “Subscription not successed”
Aside from the fact that it's not proper English, it doesn't adequately explain the situation to the user. I'd like to change it to "You have already subscribed to comments on this lesson." but it doesn't appear in the Phrases list.
Thanks in advance for your help.
