Eirepreneur are asking irish bloggers to tag their del.icio.us entries with the tag
for:oid where stands for Open Irish Directory.
You can paste this slightly modified post to del.icio.us button to your links Toolbar and it will add the tag automatically.
Of course this link won’t work as it just posts to my del.icio.us account, doh!
Ok, this just requires a bit more work on your part.
+'&tags=for:oid'including quotes at the end of the entry
Now test by posting an entry.
