Easy if you know I'm sure but I can't seem to get the members member type. I'm just trying to show an extra link in the navigation bar if a member is of a certain member type.

Here is where I'm at

@inherits umbraco.MacroEngines.DynamicNodeContext
@using umbraco.cms.businesslogic.member
@using System.Web  
@using System.Web.Security
@*
   Macro to display child pages below the root page of a standard website.
  Also highlights the current active page/section in the navigation with
   the css class "current". 
*@

@{ 
   @*Get the root of the website *@
    var root = Model.AncestorOrSelf(1);
  var classtmp = "";
}
<ul class="nav">
    <li><a href="/">Home</a></li>
    
 @foreach (var page in root.Children.Where("Visible"))
    {
       if (@page.id == 1084) {
          classtmp = "join";
       } else {
         classtmp = "";
       }
        
     <li class="@classtmp @page.IsAncestorOrSelf(Model, "active", "")">
            <a href="@page.Url">@page.Name</a>
        </li>
    }
    
 
  @{
        var m = Membership.GetUser();
          if (m!=null)
       {
        //IF member is of memberType X show this link
           <li><a href="/hiddden-link/">@m.UserName</a></li>
         }
     } 
 
</ul>
