hey @dominic I think the invite system would love this attention.

Can you clarify - ebt is not involved at all here, but ooo is, correct?

My thoughts about implementing this were to use @mikey's awesome bot framework - I'm super keen to see pubs as things you can send a message to and have them execute commands - in this context "pub my friend Emiliy is inbound, can you make me an invite for her, and also handle all that stuff when she arrives, like introducing us, and following her".
All that communication could be done as PMs with the pub, and the butt-chain then becomes the log of actions the bot has taken, and needs to take.... if the bot uses the private thread with you can also observe the progress.

Fun bonus idea - don't use a string code, which is ugly and confusing and easy to copy wrong, use an image with the code stenographically embedded in it:

(this image does not have anything embedded in it.. to my knowledge)
