[Pharo-users] Automating release announcements

Hi!, Anyone here is moderator in the Pharo Users list? I want to automate the release announcement of projects in github/ba-st org. I'm using sendgrid to send the e-mails and I'm getting a returning mail saying: "Your message to Pharo-users awaits moderator approval". I subscribed previously to the list the e-mail account used as mail sender. Thank you for your help! Gabriel
