[Koha] Koha 2.2.0RC4 translation question

Good eve, Have installed Koha 2.2.0RC4 and know i'm interested in translate it into Spanish I have recived an answer of another member about it. But first i'd like to know if is possible to perform a tranlation under previous circumstances, meanning just editing the .tmpl files with a plain text editor. (the way I did with ver. 2.0.0) Would work that way? since all about the PO file and all that seems a little bit complicated to me. I know that may take more work but I'm more used that way. I'm checking the partial translation es_AR and seeing out how it goes.... OK thanks cheers Jose Luis DEC 10, 6:12 PM
