Alright, I discussed with the Board and the option of setting an email is alright.
Do you need any additional information ?

Last election we had 40 voters.
The vote is open to every Wikimedian.

Thanks for the reply and the processing of the request.

I have a similar problem with this file: https://commons.wikimedia.org/wiki/File:An_Anglo-Chinese_Vocabulary_of_the_Ningpo_Dialect.pdf
The thumbnail is not displayed even though the file is readable after being downloaded.
