There's also some effective ways to use Threads for this if you are confined to one channel, especially on Discord where Threads hang tied to their channel and get useful names where the names can be things like books.

On Discord you can also experiment with making your "one channel" a Discussion Forum channel instead and then everything is discoverable threads. Some of the busier Discords that will only give you "one channel" for your group will often be amenable to letting that one channel be a Forum channel.
