Of course Timothy is outstanding, but you can't expect that from every
translator. Translating pages is very time consuming and not that big
fun, so I understand if one starts a translation but does not manage
to maintain it over a long period of time.

This is okay as far as you add a revision note to the page and
preferable announce off time on the ML.

Btw. I thought Ernesto Celis and his crew wanted to take care of the
Spanish pages?

Best Regards
Marcus
