I have modified the rules at
http://meta.wikimedia.org/wiki/Wikinews/Start_a_new_edition
New: At least 3 signing users have to be Wikimedia regulars (>200 edits + 3 months participation in a project) in the language they vote on.
Now formally written down: After creation, a message will be sent to wikinews-l, foundation-l and the Wikipedia Village Pump in that language.
If these rules are acceptable, they should be merged into the policy for new languages. I also think the requirement of a "reporter" should be taken out, it seems somewhat over the top.
On a different note, I am happy with the progress of the new editions. Swedish, Spanish and Dutch now have very professional looking homepages and a regular output of stories. Translation from one Wikinews edition into another seems to be more common than direct translation of Wikipedia articles.
Regards,
Erik
