As being the co-ordinator of the translations teams for Webmin/usermin and Virtualmin for nearly 2,5 years I am happy to help Virtualmin Pro to the next stage.
So if you need help in translating your modules into your language I will be happy to answer all of your questions.
It sounds like you’re interested in helping out with the Spanish translation – that would be great!
If that’s something you’d like to contribute to, Jamie would love to hear from you… you’re welcome to email him directly at jcameron@webmin.com. Put something like “Virtualmin Spanish Translation” in the subject line.
