Hi,

I have a bot if it necessary (I should ask a permission to run this task before).
But there is a ready to use tool for this in MediaWiki, which is available for Commons administrators: Special:MassMessage

Best,
Samat

Hello all,
I've found that some participants haven't yet entered their mail address in their preferences. It's required if french competitions rules (and I think in many others) so that we can contact the winners.

Is there any botmaster there that could do something to leave an automatic message on participants talkpage to warn them ?

Thanks
