Pretty EZ, when you're in your groups home page (and I mean the home tab). Then you'll see all the way on the right-part a link called: "Halo2 Clans". Click it and somewhere in (and if I recall corectly the second part of the text) that page you'll see as normal text a link called "add clan" or something like that.
The rest I think you can manage.
