When creating a new group, GroupSpot only requires you to provide your Group Name. Adding the bells and whistles like your group images, Group Header and Group Avatar, are optional in the start-a-group process. Those can be added later.
Over the next few screens you will select your Group Type, decide Who Can Join the Group, determine Who Can Post & Comment, and decide whether your group is Searchable or Not Searchable.
Even the final step, adding Membership Questions, is not required. Those too can be added later.
