I thought about the confusion "Salvador" could cause, but since other
cities/countries had "San_"/"El_" prefixes, I thought it'd been OK.
"Bahia" is likely to be a good choice.  I had thought of other cities,
like Porto Seguro (which has historical meaning: it was the very first
european stop in South America; now it is a very popular touristic and
resort city) or the city of Ilhéus, another of Bahia's largest cities.

Not really.  You can just type any e-mail (even non-existant) and pass-

I checked presidential web site all day and saw nothing, but Vitor was
successful in finding relevant information in the Ministry for Ores
and Energy's web site.

I believe you're right.  But... who can say anything is right about
Brazilian rules at all? :)  (I live in Rio, and I can testify the
chaos caused when our mayor (who is in the office again now) wanted
to extend summer time only here (and he already said he wants to do
this again this time).)

Let's see if I do it right next year (when rules will probably change
