Yes, there is an issue with the mailing system.
No, Scirra is likely unaware of it at the moment since the boys are on holidays.
So please, no need to spam the forum or support to complain about your email box getting spammed.
The issue will be fixed, the boys most likely will be sorry for it once they know it since it's definitely not intentional.
If you still feel the need to complain, please take it to this topic.
Any other message related to the issue and not posted in this topic will be moderated.
Thank you and sorry again for the disturbance.
Edit: The issue shall be fixed now.
