Spanish translation

The Spanish translation is very poor.

I have completed the translation by my own and each time there is a new version I need to check if there is any new label.

Perhaps my translation is not perfect, but it is much better than original (which has a lot of errors and many words without translation).

Here it is my file. Perhaps you think it is a good translation and include it in your next versions.

The file.

How can I attach a file in this forum?

It says: "File is not found"!
