I am writing my own role provider which inherits from "DotNetNuke.Security.Roles.RoleProvider". When i write method to delete a role group, the default parameter being passed is of type rolegroupinfo object. The question is, what is the difference between a rolegroup and a rolegroupinfo object. And could someone throw somelight on how to delete a role group by not using DNN methods, but instead by using System.Web.Security or some other microsoft namespace
