We have recently switched the site to WordPress, which gives us quite a bit more flexibility than the old site as far as editing content. It also gives it this nice new look!
We have also just added a !peak command that will show you the user peak of your channel.
<%ChanStat> (Peak): The peak user count for #chanstat is 38 and was observed on Fri Nov 08 05:49:23 UTC 2013 (1 day, 12 hours, 51 minutes ago)
We have only been logging this for a few days, so peaks older than that will not show up.
