Many servers have roles channels that let you opt into channels with various themes.
For the #RhysDarbyFaction Discord, in the #Reaction-Roles Channel, you can select an icon that corresponds to a set of channels you may want to opt in or out of.
To do so, click the emoji below the post, and that will assign you the role, and that's it! Super simple.
We can always add more roles at a later date, depending on personal preferences.
