Good news, @absay, your request has been approved!
You now have access to es_MX.

If you are not a member of OpenTTD yet, you will receive an invitation shortly (or click here).
You will have to accept this invitation before your membership is updated.

You can login to eints to start working on the translation.
Feel free to talk to your fellow translators in your Team.

Thanks.

It keeps saying my access is denied when I try to edit the language. Am I missing something?

To quote what @DorpsGek just said:

(including a useful link! :D)

You haven't yet, and as such you haven't joined the OpenTTD organization yet. This is an action you have to perform before permissions can be assigned :)

Oh, I'm sorry, I need to learn to read better, lol.

Okay, I have now joined the OpenTTD organization via the link provided by DorpsGek.

Okay, I have now access to the translator! :D

Thank you very much! And sorry for all the trouble!

No worries :) You are not the first to miss that part, and you won't be the last :) GitHub also send an email btw.

If you have tips for us how to make this part more clear, I would love to hear!

Tnx, and enjoy translating :D
