Concise description: When responding to a pm have an additional button at the bottom of the screen titled 'reply to all'.
Specifics/Details: As it is now when a player pms more than one person. the recipient must add all the other recipient's names manually if he/she wishes to respond to all. This could be automated through an additional button.
How this will benefit the site and/or other comments: It would make group discussions via pm easier.
