Spanish Raws

i think you're free to do what you like...
you could also join a scanlation group if interested :D (๑•ㅂ•)و✧

No you don't need a certificate or anything. You can join a scanlation group or you can individually do the translation and type-setting and other stuff. In fact many scanlation teams look for people to translate a Manga into another language. Most groups allow fan translations in other languages provided you aske them for the Raws first.
Thank you for spreading the love of manga :)

Thanks both of you for the info. Sorry but I have more questions. ┗( T﹏T )┛ If I were to pick a manga to translate then would I HAVE to ask the group who is already translating it in English or the ones who have translated it in Spanish since I'm basing it off of them? And if I did have to then how do I get in contact with them? Also would I simply just submit it to mangago or would have to post it some place else? I would rather do this individually(⌒▽⌒) Sorry for asking so many questions.

Just find a Spanish scanlation group and their site. They always put how you can contact them, and whether you need to ask them for permission to retranslate.
when you are done with the chapters, you need to upload them on sites like sendspace or something and then send mangago a link.

Thank you for this information!!!
