Surprised DizzyDoo's videos aren't posted here.
Anyways, this tutorial is a basic chatroom tutorial, including private/normal messaging, connecting and disconnecting.

I shall update the MFA and EXE and post links to those soon
Currently they're using an old version iirc, so the EXE won't connect, and the MFA needs a new Connect action (#19 -> #20 Connect action went from 2 parameters to 1) before it'll work.
It was written for OINC originally (that's how old it is!) but I've updated to #19-ish. Enjoy.
