Any thought's on this yet?
What I am suggesting is adding a comment box below the game on each game page.

I had at one time html comment box as well as face book comment box on my game pages on my live test site.
I didn't like either.
Using the html comment box, each member would have to add their name and for admin to edit any comments you would have to go to html comments site to do that.

And face book just sucks...
