Hello guys
I just downloaded the translation package into Spanish for zencart from the downloads section and it turns out that the translation is more or less ok. The problem is that somethings are not translated. For example: when I am visualizing a product, there should be some pictures which say:
"tell us about a friend"
"add this to my cart."
Well these previous messages do not appear in the Spanish translation and instead there are just two corresponding empty squares.

Having said so, I would appreciate if anybody could not only give me a solution for this particular translation but to tell me what the procedure is to create new translations. It's not that I am thinking on create a new translation but I might think about modifying some little parts of some translation packages I might download like the one into Spanish I just mentioned.
Look forward to seeing your reply soon.
Thanks in advance
