How can I vote in another country?

[EneME]

I was born in El Salvador, but have U$ citizenship. I want to vote in the upcoming elections in March for the presidency in ES. Anyone have any suggestions on how I could do that?

I'm guessing that unless you renounced your Salvadoran citizenship, then you probably only have to prove birth, and get an absentee ballot. I would call the Salvadoran consulate here in the U.$.
