The imperative is still a bit up in the air. In a survey I did on a class
of gymnasium students I got the following results:

bitt - 8 students
bind - 5 students
bint - 4 students
bindt - 2 students

The last one surprised me since it doesn't confirm with normal Icelandic
orthography, we don't get 'dt' clusters.
