puddy - the fact that an email address was not listed on the job ad is fact enough that submissions should be snail-mailed. Remember, at this point, thinking outside the box will not help you
Plus if one of 250 CVs has to be printed.... you get my drift.
Send it in and you'll be lucky enough that the emailed version made it nowhere.....we hope.
I recently went through the whole search/apply process and found a nice looking job for an IT company who wanted CVs via snail-mail. I did not apply
