Why is this so confusing to me?
Because it's not yet finished.
All your actions will go through the parser.
When it's done, the parser will record your actions together with all the expenditures and gains.
It will then give you a "token" - a short string - that you post together with the roleplay. The token can be verified by every other player.
So all the posting will always be done by you, and you can make sure it goes to the proper place.
But you will add the token string to your posting, and that will allow other players to check that you actually are capable of casting the spells that you used in your roleplay.
