Storyteller's Circle maintains a Discord channel for use by our members. You will need to integrate your Storyteller's Circle account with a valid Discord account before you will be able to send messages outside of the new-members channel.
Your accounts can be linked through your connected accounts settings:
The integration system can be a little delayed in updating permissions, so if you have linked your accounts and still can't send messages to the Discord after ten or fifteen minutes, feel free to post a message into the help channel on the Discord and someone will usually be happy to manually update it for you if they're around.
