I am starting a wiki+forum in Spanish language, for an audience who might not have enough “internet savvy” and may be less than fluent in English, so it would be very useful to have everything in Spanish. I hope to contribute to Spanish translation if the possibility comes up.
Pages created from templates, I can translate them. My concern is mainly with “system” pages, such as login, warning and error messages, etc.
One way to have translations sooner would be to put all “system” text as pages on this wiki, say under to-spanish:, and let wikidot users translate them. Then, when translators give their thumbs up (if needed), you can upload such translations to the server. (I know you already thought about that, I am just voting. :) )
