Add bookmark to pinbord.in with predefined tag, without user intervention

gistfile1.js

javascript:q=location.href;if(document.getSelection){d=document.getSelection();}else{d='';};p=document.title;void(open('https://pinboard.in/add?later=yes&noui=yes&jump=close&tags=TAGS GO HERE&url='+encodeURIComponent(q)+'&description='+encodeURIComponent(d)+'&title='+encodeURIComponent(p),'Pinboard','toolbar=no,width=100,height=100'));

// Copy and paste the above into a new bookmark. Replace "TAGS GO HERE" with your tags. Presto!

Is there any way to get this to not be Read Later? Even when I change later=no, it still ends up marked as "to read".

So sweet, thanks!
