For usability purposes you may want to consider keeping the page name in the breadcrumbs but not linked (maybe bold it)

Here is how we do something like that:

~/Admin/Skins/BreadCrumb.ascx.vb:

take this line:

If objTab.DisableLink Then

                    strBreadCrumbs += "<span class=""" & strCssClass & """>" & strLabel & "</span>"

Replace it with:

 If objTab.DisableLink Or PortalSettings.ActiveTab.TabName = strLabel Then

                    strBreadCrumbs += "<span class=""" & strCssClass & """>" & strLabel & "</span>"

                Else

Then, assuming your class is "crumblink", put this in your stylesheet:

span.crumblink{
    font-weight:bold;
    font-size:1.1em;
}
