Sharepoint 2010 Custom Field type

Question

I tried creating a custom frield type using the articles "Creating a Custom Field Type for SharePoint 2010 (Email Validation Field)" and MSDN article "Creating Custom SharePoint 2010 Field Types". In both cases I dont see any build /deployment errors. But still I dont see the custom field type in the list of options when I try to create a new column. Do I need to do anything on the Central Adinistration to make this work. Please help me with this.

Sorry to ask, but has the feature been activated in Site collection features — ben

The code is working fine now. Other than the steps mentioned in the articles I also added below code.

protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);

            // add save handler only in New and Edit modes
            if ((SPContext.Current.FormContext.FormMode == SPControlMode.New)
                || (SPContext.Current.FormContext.FormMode == SPControlMode.Edit))
            {
                SPContext.Current.FormContext.OnSaveHandler
                    += new EventHandler(MyCustomSaveHandler);
            }
        }

        protected void MyCustomSaveHandler(object sender, EventArgs e)
        {
            Page.Validate();
            if (Page.IsValid)
            {
                SPContext.Current.ListItem["CM_x0020_Number"] = TextBox1.Text;
                SPContext.Current.ListItem.Update();
            }
            else
            {
                // do actions instead of save
            }
        }
