For those who are following and regularly attend Mass at Immaculate Heart in Akron (Father Carley's chapel), Mass will be at noon again on Sunday. NO 9AM MASS. Unfortunately, last time SSPX did this, many people showed up at IHM at 9AM only to find a sign on the door that there would be no 9AM Masss (just noon). Father Carley has never been very "techie" and so he has no good way to get news out about schedule changes, and really has never needed to in 40 years, as he'd not missed a day before now (except once for his hip surgery).
Maybe he could have someone at the chapel who is more technical, to maintain a kind of mailing or message list, so that people could be notified if Mass is cancelled on short notice? Or failing that, even something as retro as a "telephone tree"?
I once attended a TLM site which was similarly low-tech, and my wife and I got there, only to find a sign taped to the door, "NO LATIN MASS TODAY". They had no bulletin, no website, no nothing. Good thing we hadn't driven 100 miles only to find that out.
