Hello Joachim,
It took me a moment to realize that this sentence "easy for translators (do they need the full IDE? poedit?)" was already on a very old version of that page in the wiki, and it was written by myself, long before we made decisions about which tools to use for translation.
I have now cleaned up some of the pages on the wiki related to translations, and mainly removed parts of sourceforge.net/apps/mediawiki/ ... Developers which used to have the title "HowTo help with Translation". It links now to your page "Documentation for Translators".
Wolfgang has added documentation about the formatting of currency values on that page "Comparison I18N", because it is related to i18n/localization.
