Amazing! The tool has gone through over 1500 posts - over two years worth - and has worked perfectly. (It's now paused at about 60% done - I seem to have the RC still (74%), but oh well, I guess it will do more later.) Thank you so much!
(Now to write up a "so long and thanks for all the fish" post to Justin.)
Still not resuming after the Steem outage there... Has he managed to block this tool already?
