Hi Jacobo, thanks for your offer, I appreciate it greatly!
Our sources of information are at https://meta.wikimedia.org/wiki/Tech/News#contribute -- we go through them every week, so if you'd like to help out, I suggest you check them on Tuesday or Wednesday and add items you find important (or just links) to the next issue which will be developed at https://meta.wikimedia.org/wiki/Tech/News/Next
If you'd like to help out with translations, the latest issue hasn't yet been translated into that language: https://meta.wikimedia.org/wiki/Tech/News/Latest -- all help is welcome :-)
