Took me awhile but I finnally finished this code that was requested by LittleKidder,. Here is the code.
You can accually change any words that are in the post profile area, the Custom title, Member group and more! You may use HTML in the "NEW TEXT" part, just don't use double quotes, use single.
Place in Headers or Footers:
<script>
function replace_text(find,replace){
//Created by Agent Moose at smcodes.smfforfree3.com
a = document.getElementsByTagName("div");
for (i=0;i<a.length;i++){
if(a[i].className=="smalltext" && a[i].innerHTML.match(find)){
a[i].innerHTML=a[i].innerHTML.replace(find,replace);
};};};
replace_text("OLD TEXT","NEW TEXT");
</script>
