Most WMAs have sign-in hunts and quota hunts. You have to apply early for quota hunts, but you can just show up for sign-in hunts. Quota hunt applications are now online and can be found at www.gohuntgeorgia.com. Good Luck.
Most of the WMA's have either sign-in or check-in hunts for the gun hunts. The more popular WMA's have quota hunts to limit the number of people on the area. The mountain WMAs don't have as many quotas since they are so big and not too many people per square mile compared to the piedmont area of GA. You can still sign up for a quota hunts on-line.
