According to what was said in http://www.wgt.com/forums/t/108609.aspx?PageIndex=3 I have a suggestion for you WGT.
As it is a real pain going through "take Screenshot-paste in paint-save-find support email on this site-log in to mail-write mail and issue-send mail", I would like to see an easier way of doing this.
And another thing is that a screenshot only fits like 4 rows of chat so it sometimes would take many many screenshots to get the whole picture. And some people can even be faulty accused as the person sending the screenshot might have started and said worse things but only sends what the opponent said.
So what I suggest is that you add a button, much like the the bug-button "submit this problem to WGT". This new button could be something like "sumbit this abuse to WGT" and what it does is: A pop-up comes up and you can write some lines about what you think about the situation. The text written in the pop-up will then be sent along with the whole chat for the game.
Then no misunderstandings, nice and easy way to report abuse instead of the pain in the ... way i mentioned above.
Sincerely
SP
