Re: opening up editing privileges?
Naturally a GM wouldn't allow one player to post on behalf of another without the absentee's permission, but the facility would be additionally useful in 'farming out' NPCs to other players.
I ran a game recently in which I had a number of redshirts in the group and wanted any of my players to be able to post for any of the redshirts to keep the game flowing. I managed a workaround, but a 'post as' puppeteer mode would be useful.
The current GM facility shows a simplified personal box to the left of the post which currently doesn't even show a portrait. I'm picturing something very similar, that would be an obvious puppet post, having none of the personal data, but I'd like the facility to include a portrait if one has been created.
