I've tried using the "Contact Participants" button as the organizer of my event but it's not being received by the participants. The message says the email was successfully sent. I am able to click on a participants email diretly on the event and it's received. I use Acymailing to send out announcements to the club members which works fine so I don't think it's an issue with the system. Is it possible that their is a bug on my Matukio version 7.0.11?
