Hi!
While reviewing possible argentinian sponsors, I realized that what we
give back to sponsors is too little. So I came up with an idea (that
then turned out not to be that original):
We could print a short magazine, that includes interesting info about
the conf, about Mar del Plata, about Argentina, DebConf schedule,
talks abstracts, etc. And in this magazine include ads from the
sponsors.
This could be done with the proceedings, instead of a magazine. I
personally don't like the proceedings too much, because not many
people read them, and they tend to be a waste of paper, but the result
would be the same.
