You can identify users that already visited your site with cookies...

Once they registrate you make a cookie with their name and once they come back you look tof this cookie...

Than somewhere at the top of your page you write...

//for those who don't have a cookie
Hello and welcome! If you are registered user, you can sign in here...
If not registered, you can register here...

//those with cookies
Wellcome again, Andrew Long. ....

You need a code for that or just the idea???

save this as cookie.js

// --- start of cookie.js file
if (!window.daysToKeep) daysToKeep = 365; // default cookie life...
today      = new Date();
expiryDate = new Date(today.getTime() + (daysToKeep * 86400000));

/* Cookie functions originally by Bill Dortsch */

function setCookie (name,value,expires,path,theDomain,secure) {
   value = escape(value);
   var theCookie = name + "=" + value +
   ((expires)    ? "; expires=" + expires.toGMTString() : "") +
   ((path)       ? "; path="    + path   : "") +
   ((theDomain)  ? "; domain="  + theDomain : "") +
   ((secure)     ? "; secure"            : "");
   document.cookie = theCookie;
}

function getCookie(Name) {
   var search = Name + "="
   if (document.cookie.length > 0) { // if there are any cookies
      offset = document.cookie.indexOf(search)
      if (offset != -1) { // if cookie exists
         offset += search.length
         // set index of beginning of value
         end = document.cookie.indexOf(";", offset)
         // set index of end of cookie value
         if (end == -1) end = document.cookie.length
         return unescape(document.cookie.substring(offset, end))
      }
   }
}
function delCookie(name,path,domain) {
   if (getCookie(name)) document.cookie = name + "=" +
      ((path)   ? ";path="   + path   : "") +
      ((domain) ? ";domain=" + domain : "") +
      ";expires=Thu, 01-Jan-70 00:00:01 GMT";
}
// -- end of cookie.js
