I'm trying to create a new forum member at the same time I create a new umbraco member and have the ability for them to auto sign into their forum account when the log into their umbraco account. 

however, I'm having some really issues trying to dynamically create a forum member.

For an umbraco member I'm doing the following

    Member newMember;

    MemberType demoMemberType = MemberType.GetByAlias("Member");

    private void SomeMethod(ModelClass newEmployee)

    {

        if (!memberSevice.Exists(newEmployee.FirstName + newEmployee.LastName))

        {

         newMember = Member.MakeNew(newEmployee.FirstName  + newEmployee.LastName , demoMemberType, new umbraco.BusinessLogic.User(0));

        }

        else if (memberSevice.Exists(newEmployee.FirstName + newEmployee.LastName))

        {

          int count = 0;

          count = count + memberSevice.Count();

          newMember = Member.MakeNew(newEmployee.FirstName + newEmployee.LastName + count, demoMemberType, new umbraco.BusinessLogic.User(0));

         }

          newMember.getProperty("firstName").Value = newEmployee.FirstName;

          newMember.Save();

    }

But when I tried doing the same but changing the Alias to both DialogueMember & Dialogue Member the new forum member isn't created. I know how to edit existing forum members by grabbing their ID number (which I need to hardcode) and i'm able to log in when my user logs in (but again, these are hardcoded in).

I've got a feeling that this isn't working due not being able to generate a unique user ID for Dialogue Members and I was wondering if someone could tell me what it is I'm doing wrong and how I can fix it
