I would just like to ask players to please be mindful of the storytelling and immersion of others and avoid Local OOC chatter as much as they are able during large plots and public events where there are a lot of players present. What can be perfectly acceptable in 1-on-1 or small group roleplaying is not always ideal in large groups where you may not know everyone's feelings about it.
Really no one will mind if there happened to be a typo in a pose or description and these sorts of things don't have to be pointed out until later. Just imagine you're performing in a play, and it's waiting to get off the stage before commiserating about forgetting a line.
