Hey Jenny,
French
PR distributors are usually more national than multilingual. Most of good resources that i know only suggest publishing in french language.
Also French
PR is not as much developped as English or American
PR, notably in terms of
ONLINE PR, so one can't find as many resources as these last languages.
However, i noticed things start moving in the field and few websites now like
http://www.free-press-release.com/ are developped and give you the chance to post for free your release in french and at least in english version too!
