Hi Mark! First of all: Thanks very much for your support and help!! and my apologies by the mistakes in the files. We used a HTML editor, and I didn't review the files.
I reviewed all templates, and I fixed it. Can you do a quick review and upload these templates, please?
Everything looks good except for one thing. The postack.txt template is as follows:
El to mensax tocante a:
distribuyóse de mou correutu a la llista %(listname)s.
Páxina d'información de la llista: %(listinfo_url)s Your preferences: %(optionsurl)s
I added the last line which was missing in your original. The phrase "Your preferences" still needs to be translated.
