Sometimes, I really have a heck of a time searching on this forum. I am trying to find a post that was within the last six months. Folks were posting favorite churches, or don't miss Rome churches. It was a rather extensive list. I think at least 10 people replied with contributions. I've searched within the forum and using an external browser. Does anyone recall this post? It might have been this, which was unfortunately deleted. Which, WHY??

I do have the recent post that linked a magazine article of about 5 churches that tend to not be crowded.
