Our head programmer just released the ability to edit league message board comments, forum comments, and news item comments.
There is now an "edit" link when you mouse-over a message you posted (you can't edit the initial title of your message, but can the body/contents).
Let us know if you see any errors. There is no timestamp with the edit or a reasoning for the edit as of now.
Your feedback is important, so let us know what you think.
