So are you going to embed a list of 'My comments elsewhere' on your blog? Cause that would be awsome!

wow, pretty cool idea, that relay solves my problem of remembering places to come back to. @adrian this sounds like a foaf for plogposts

@Adrian, yeah that was the original intention, but I just never got around to it. It'd be dead easy to add via the standard del.icio.us javascript linkroll.

Clever thing!

Andrew, clever idea, thank you, now to make use of the basic tools available on del.ico.us

I translated the messages of output to spanish. Maybe u could put a "spanish version" to download. Sure some will use that ;).

Greetings and congratulations for this work Andrew!

Nicolas.

HERE IS THE CODE:

Validation.addAllThese([
['required', 'Este campo es obligatorio.', function(v) {
return !Validation.get('IsEmpty').test(v);
}],

return Validation.get('IsEmpty').test(v) || /w{1,}[@][w-]{1,}([.]([w-]{1,})){1,3}$/.test(v)

['validate-url', 'Por favor ingrese una URL valida.', function (v) {
return Validation.get('IsEmpty').test(v) || /^(http|https|ftp)://(([A-Z0-9][A-Z0-9_-]*)(.[A-Z0-9][A-Z0-9_-]*)+)(:(d+))?/?/i.test(v)
}],
['validate-date-au', 'Por favor use este formato de fecha: dd/mm/yyyy. Por ejemplo 17/03/2006 Para el 17 de Marzo de 2006.', function(v) {
if(Validation.get('IsEmpty').test(v)) return true;
var regex = /^(d{2})/(d{2})/(d{4})$/;
if(!regex.test(v)) return false;
var d = new Date(v.replace(regex, '$2/$1/$3'));
return ( parseInt(RegExp.$2, 10) == (1+d.getMonth()) ) && 
(parseInt(RegExp.$1, 10) == d.getDate()) && 
(parseInt(RegExp.$3, 10) == d.getFullYear() );
}],

// [$]1[##][,###]+[.##]
// [$]1###+[.##]
// [$]0.##
// [$].##
return Validation.get('IsEmpty').test(v) ||  /^$?-?([1-9]{1}[0-9]{0,2}(,[0-9]{3})*(.[0-9]{0,2})?|[1-9]{1}d*(.[0-9]{0,2})?|0(.[0-9]{0,2})?|(.[0-9]{1,2})?)$/.test(v)
}],
['validate-selection', 'Por favor haga una selección.', function(v,elm){
return elm.options ? elm.selectedIndex > 0 : !Validation.get('IsEmpty').test(v);
}],
['validate-one-required', 'Por favor seleccione algún ítem.', function (v,elm) {
var p = elm.parentNode;
var options = p.getElementsByTagName('INPUT');
return $A(options).any(function(elm) {
return $F(elm);
});
}]
]);

I needed to localize the validation library so this is what I've done (look at the sections enclosed with ////// ADDED ///////////// and ///// CHANGED /////////)

Thanks for the post. One side note, the current bookmarklet is v4 and doesn't pay attention to the tags variable. The only way I got it to work was to change v3.
