Please consider adding one step between writing the message and sending it, so the sender gets one last chance to make changes. On chessgames.com there is a "Preview Kibitz" option right next to the "Post Kibitz" button so we have another mechanism to reread the text for typos and syntax errors. Several times I have caught mistakes in my messages only after they're sent, requiring a second message. Another idea would be to add the "pencil" for messages which would allow us to correct mistakes.
It's not just a point of semantics. Many users don't have English as their primary language, so sending "good game" versus "goof game" makes a huge difference.
