Am trying to connect the forum with my website and in the process need to create a user session in the forum without the user having to login.
When the user registers on my site I simultanously create the necessary enteries in the 4 tables of the forum but can anyone guide me how I can create a session in the forum so that the user doesnt have to login to the forum explicitly.

MembershipUser user = Membership.GetUser("testuser");
if (user != null && HttpContext.Current.Session["UserUpdated"] == null)
{
//HOW DO I CREATE THE USER SESSION HERE
HttpContext.Current.Session["UserUpdated"] = true;
}

All help is highly appreciated.
