System emails do not pertain to the forum. These are emails that are sent out system-wide so that all members receive notification of ongoing events. I'm sorry that it seems that you are receiving too many, but we have had some Administrative changes lately, which has resulted in several more system emails than usual.
You will also be receiving a system email, soon, regarding our upcoming fundraising drive to keep the site open. Again, I'm sorry they seem excessive lately, but we are slowly integrating the new Administrators.
As you said, though, you could choose to turn off emails altogether - at this point, that would seem your only option.
Without Miss Kagura to do the coding, we have no programmer to monitor the site or work on feature requests at the present time. Since our big push for funding for hosting is coming up, we also do not have the funds to hire someone to do the programming. My apologies for your inconvenience.
