I found this site http://www.mesadeayuda.org and it is too similar to our good old Stack Oveflow.
Is it supposed to be a Spanish version of it? (BTW: MesaDeAyuda means 'help desk')
The official Spanish Stack Overflow site is coming in late October/early November of 2015. Work for the new site is set to start on August 1st, 2015!
This will not be a sister site but rather an official Stack Overflow site for Spanish speakers just like the Russian, Portuguese and Japanese SO sites.
I hope to see you there!
Stack Overflow en español is alive and well!
