Here is a summary of other ways you can stay up to date from Bill Lewellis, Diocese of Bethlehem Communications officer:
Two of our clergy deputies at General Convention have been posting reports on their blogs several times daily. Anyone who seeks some flavor of what’s going on in Columbus from a deputy’s point of reference/view will get just that if they read Andrew Plus, the blog of Andrew Gerns, rector of Trinity, Easton, and Entangled States, the blog of Nick Knisely, rector of Trinity Church, Bethlehem.
Then there’s the special GC site provided by Episcopal News Service, a great service where you can download the Convention Daily newspaper and watch the Convention Nightly newscast.
