I read a thread where someone wasn't sure if they should alter an other poster's image as a short cut for criticism.
I then thought, wouldn't it be cool if user could have a resource one shop stop to find out if other users mind having their image changed or not.
Don't worry if your answer is no. I'm sure no one would be crass enough to call you out on it, amirite?
If this thread takes off, maybe it be stickied?
My answer? Yes, feel free as long as the crit is con.
