Before we go with community translations, I'm currently discussing about how it can be done right. There are some considerations. Like potential inaccuracies in translations or translations that don't get updated often enough. So it's most likely that the english texts are going to be proof-read many times in the future before being published (and translated). Some translation guidelines are also needed.
Personally, I want the website to be translated in as many languages as possible (as long as each transaction is accurate and good quality). So you can count on me to come back about this if nobody opposes to this idea.
Thanks for offering yourself!
Congratulations on the upgrade of your work to bitcoin.org!
About the guidelines and the translation process there are the following issues I see:
1) The translations must be kept up-to-date
2) The quality must be high
As I understood this project is set up this way (on github where pull requests are invited) to be able to translate everything, including things like urls and rewrite rules thereof. But there are downsides to not using a tool like transifex: Especially issue 1) becomes a problem I think.
Is there an easy solution to let translators know which sections in the source (English) have been updated since their last translation efforts? Maybe a very detailed summary should be written every time something changes in English? I've noticed in bitcoin-qt that sometimes a wording in the source changes only slightly but results in a big difference in meaning. If you don't know there has been such an update it is very easy to miss it when you compare a source and its translation side by side.
Regarding the quality issue (2): Should we maybe require a small team per language, so that we only let a language go live if there are at least say three people vouching to look after the translation?
Surely there is some experienced web developer here who has managed a high-profile multi lingual website?
I'd be very happy to contribute the Dutch translation, I've done also the bulk of bitcoin-qt so I can make them consistent.
