I'm a sysop on French wikisource, I have lost my password and I have no
email address to ask a new password.
Explanations here :
I know it is possible to insert a new email address in the database, so
I look for someone who can access to it.
Thank for your help.
You have to ask someone on #wikimedia-tech, but you'll probably need
some sysop to explicitly confirm that you're tha ligitimate owner of
that account (for instance in the page you linked).
