Have you heard of our Archbishop John-Charles Vockler? I believe he was instrumental in bringing the ACC and the APCK together. I could be wrong, but I remembered something liek that being announced last year.
It's only recently I've begin to pay attention to the (Anglican) world outside my own parish. I do know there have been conversations between the ACC and APCK, last fall as I recall it being reported by FIFNA. I have also been told that the APCK and the ACA(/TAC) have recently established grounds for cooperation, hopefully an initial step towards unification. I would like to see these progress.
