Hi Peter,

Dust... high in fat, low in fat? ;-)

There isn't a way to disable the Content Channel from the user edit screen, so you have 2 options:

1. Manually add the following CSS to the "/umbraco/users/EditUser.aspx"

<style type='text/css'>#body_UserTabs_tab02{display:none;}</style>

The only problem is that this would be overwritten if you upgraded Umbraco.

2. Use code to hook into a back-office page event to auto-insert the same CSS, like so...

using System;
using System.Web.UI.WebControls;
using umbraco.BusinessLogic;
using umbraco.presentation.masterpages;

namespace Our.Umbraco
{
    public class HideUserContentChannel : ApplicationBase
    {
        public HideUserContentChannel()
        {
            umbracoPage.Init += new MasterPageLoadHandler(this.InjectCss);
        }

        protected void InjectCss(object sender, EventArgs e)
        {
            var page = sender as umbracoPage;
            if (page == null)
                return;

            var path = page.Page.Request.Path.ToLower();
            if (!path.Contains("users/edituser.aspx"))
                return;

            var container = page.FindControl("body") as ContentPlaceHolder;
            if (container == null)
                return;

            var css = @"<style type='text/css'>#body_UserTabs_tab02{display:none;}</style>";

            page.Page.ClientScript.RegisterStartupScript(this.GetType(), "HideUserContentChannel", css, false);
        }
    }
}

Cheers, Lee.
