This room is for general discussion that doesn't specifically fit into one of the other CatholicMatch rooms. Topics should not be overly serious as this is to be more of a "cafe setting."
Saint Peter's Square was created so that more people could be in the presence of the Pope and was named after Saint Peter, one of Jesus's apostles.

The last new entry in the stream was 30 minutes ago -- just before DST ended in the Eastern time zone (where the CM server is based). My guess is it won't start updating until the top of the next hour, when EST ticks past where DST was when the time changed.
Posting seems to work, though, so carry on!
Also, the Last Post times till be off by one hour until your time zone changes back to Standard Time (e.g., if you are stilll on DST, a post that was entered 1 minute ago will show as being 61 minutes old).
