You need to use the UserSid class. Check out this the SDK and this faq for more info: http://www.episerver.com/templates/faq____976.aspx Log in the user you have created and then use the SubscribeTo(...) method to add subscriptions. To log in a user you need to do something like this: IPrincipal iPrincipal = AuthenticationProvider.Authenticate(this, name, pass); if (iPrincipal == null) return null; FormsAuthentication.Initialize(); FormsAuthenticationTicket ticket = new FormsAuthenticationTicket( 1, name, DateTime.Now, DateTime.Now.AddMinutes(5), false, pass, FormsAuthentication.FormsCookiePath ); string cookiestr = FormsAuthentication.Encrypt(ticket); string url = FormsAuthentication.GetRedirectUrl( name, false ); Response.Cookies[FormsAuthentication.FormsCookieName].Value = cookiestr;

Thanks. I ended up with another approach when I did this earlier, and would like to post this here. In Subscribe.aspx, I use two different user controls. In page_load in the .aspx I check if the current user not is anonymous. If so, I load SubscribeAuth.ascx, which is identical the one on the Sample Site. If not, I load SubscribeAnonym.ascx. This control does the following: protected void Save_Click(object sender, EventArgs e) { if(ValidEmail()) { UnifiedPrincipal originalUser = PageBase.CurrentUser; int intInterval = Int32.Parse(Interval.SelectedItem.Value); PersonalizedData user = HandleUser(); if(user != null) { SubscriptionInfo subscriptionInfo = new SubscriptionInfo(user); //Set interval subscriptionInfo.Interval = intInterval; //Loop through list of subscription alternatives, and //add or remove from user foreach (ListItem subitem in cblSubList.Items) { if (subitem.Selected == true) subscriptionInfo.SubscribeTo(PageReference.Parse(subitem.Value), CurrentPage.LanguageID); else subscriptionInfo.UnSubscribe(PageReference.Parse(subitem.Value), CurrentPage.LanguageID); } //Save the new data on the user user.Save(); } //Show receipt SubscribeArea.Visible = false; ReceiptArea.Visible = true; //Reset CurrentUser object PageBase.CurrentUser = originalUser; } } The HandleUser method looks like this: private PersonalizedData HandleUser() { string strUserName = Email.Text; //Return if email field is blank if(strUserName == string.Empty) return null; //If user already exists, retrieve this one PersonalizedData existinguser = PersonalizedData.Load(strUserName); //Return existing user if(existinguser != null) { //Update the user's email address existinguser.Email = strUserName; return existinguser; } //Create new user else { UserSid newuser = new UserSid(SecurityIdentityType.ExtranetUser); //Add the user to the default Group int defaultGroupID = (int)Configuration["EPnDefaultGroup"]; GroupSid defaultGroup = GroupSid.LoadGroup(defaultGroupID); if(defaultGroup != null) newuser.MemberOfGroups.Add(defaultGroup); //Set the user to active newuser.Active = true; //Set user properties newuser.Name = strUserName; newuser.Email = strUserName; try { newuser.Save(); return PersonalizedData.Load(newuser.Name); } catch(DataAbstractionException error) { //ErrorOccured(error.Message); return null; } } } A bit more code, but the user doesn't get logged in with cookies and so forth, which wasn't supposed to happen in our solution.
