Hi!
Wiki is uneasy to translate, there is no useful tool such as Poedit,
Lokalize etc. to do the work offline.
In fact, TranslateWiki (TW) extension [1] offers PO export and import capabilities. KDE
uses this extension to translate UserBase [2] documentation. It is very easy to use.
Online translation memory is also included.
BTW, translation memory is not very efficient for docs translation. Moreover,
Tx.net does
not offer this at all by now.
It is also hard to know that if the source language has been updated
or not without notification.
It can be easily handled by RSS or Atom feed (the news on updates can be read right from
your desktop). Very handy.
I do not like the idea of wiki documentation much, because it breaks my workflow, but it
is already broken by migration. So it can be vital solution.
Best regards,
Yuri
