Well in Indiana you can't use rifles for deer hunting but shotguns are legal weapons. You wouldn't have to make a whole new catogory but just put Rifle and Shotgun Hunting instead of just Rifle Hunting.
In the Other Hunting Topics you could add Varmits. I could probably get quite a few guys who really know what they are doin when it comes to coyote hunting.
These are just my suggestions. Take them or leave them. Just thought I throw some ideas to you. Good luck with the site.
