I'd like to be able to comment on bugs reported by other players (that I can see). This would help enable us to be able to give more information, even if it's just a "Me too!".
I do understand that JIRA gets expensive fast when you give everybody an account, so I'm hoping it could be set up for us to be able to comment via an in-game command or even the site! Anything would be fantastic for those of us that like helping figure out bugs.
