Thanks for the tip! Were professions added recently? "Doctor of Medicine" wasn't on the list at the time we put up the ads a month ago.

For workplace targetting, it looks like none of the hospitals in our current markets (Balkans) are in the system, so it's not as useful. We had a similar problem when trying to target people with "Medical School" as education and got something like 10 people total, seems education as an attribute is counted only for US-based users.
