Not sure how easy it is but a number of various different games have the server status integrated within their webpage / forums
The main game that springs to mind it WoW. What I'm thinking is, you could just come onto the forums and instantly see whether a server is up/down and what the percentage / capacity is at - Similar to the below:
This would probably (hopefully) stop countless threads appearing with people stating they're having login problems and allow at a glance, to see roughly how many people are online.
Just a thought
Good work so far
