I think I was subscribed to Odoo mailing-lists twice because I received all e-mails in double. Is there a way to unsubscribe me to the mailing-lists ? I tried https://www.odoo.com/page/odoo-community and https://www.odoo.com/groups?unsubscribe but I never receive an e-mail to say me I have been unsubcribed.
Plus, there is no confirmation of subscription, so if I want, I can subscribe an e-mail address that is not mine and all e-mail of mailing-lists will be sent to this address even if the recipients don't want to receive these e-mails !!!
