I see in many threads that many problems main cause is uppercase problem in signup process.
Maybe i can help to minimize the problem with a little javascript.
<script type="text/javascript">
function nocaps(){
original = document.formname.inputname.value;
nocaps = original.toLowerCase();
document.formname.inputname.value = nocaps;}
</script>
<form name="formname" method="get">
<input type="text" name="inputname" value="TEXSTAERERASODHAIOSGUDAISUDGIASUDASIOUDGAS">
<input type="submit" onClick="nocaps()">
</form>
although in the input is still uppercase, but it sended with lowercase.
I think this script not so perfect, so change it to your way.
