You should add the following link to your item's pages:

javascript: location.href='http://www.thethingsiwant.com/wishing/addtolist_s.php4?type=fromsite
&URL='+encodeURIComponent(location.href)+'
& Desc='+encodeURIComponent(this.document.title);

Then you send us an email, we customize TTIWBot, and when somebody clicks on the link, TTIWBot does all the job of finding the item info.

I added an example here to show how it works (please, pay no mind to the page design, it's just an example.): http://www.metonymie.com/testeo.html
(It should work now.)

The bot should be fast now. I also added a bunch of new sites to it.

When I finnish with the sites (in a couple of hours), I'll fix the suggested sites section and then I think we are ready to move to beta 2.
(I have to fix the Amazon thingy to move to Final yet).
