Currently anyone with a game posted to the site has to go to the site to see if anyone has commented on their game or provided a review. Would it be possible to have an email sent as well to make sure that players aren't left waiting for a long time and developers don't have to watch the site every day?

+1 for that, it's a very good idea. As it is, I lurk on the forums via the newsfeed, and very rarely log in, so if someone comments on my games, or leaves me a message, it takes a long time for me to see it.
