Halo 4 stats/map downloads

I am just wondering what is the easiest way to find these maps being added tomorrow. I was bored and wanted to play around on them a bit.

Also, since I’m here, whats the easiest way to check other peoples stats. It is so counter-intuitive on this site to find stuff. I always end up going to my stats page and copy/paste their GT into the URL

Any ideas?

Thanks
