 @inherits Umbraco.Web.Macros.PartialViewMacroPage


@using System.Web.Mvc.Html
@using ClientDependency.Core.Mvc
@using Umbraco.Web
@using Umbraco.Web.Controllers
@using BlueprintUMEx.Web.Models

@{


    var registerExtendedModel = Members.CreateExtendedRegistrationModel("Member", "client");



    Html.EnableClientValidation();
    Html.EnableUnobtrusiveJavaScript();
    Html.RequiresJs("/umbraco_client/ui/jquery.js");
    Html.RequiresJs("/umbraco_client/Application/JQuery/jquery.validate.min.js");
