Hey there! VMs are a perfect way to contact me, so no worries there.
Thanks for showing interest in the project! As a starting point, send Setsuna and I a private message telling us a little bit about yourself and your ability to write and speak in Spanish. Once you do that, we will evaluate your fluency in Spanish by giving you a "test." You will receive more information about the test via PM. If we find that your Spanish is very good, we will definitely consider making you an official member of the translations project.
Also, it'd be good if you could send us the introductory PM in Spanish so we can start evaluating you right off the bat.
¡Que tenga buena suerte!
