We are thriving for spam free high quality discussion forums for our audience.
In that process we are testing some of the group features and did not realize that reply to message is sending email to every one due to which each individual got multiple emails.
We have fixed the issue and you will not get emails for each and every response. While we understood these features thoroughly if you see any unnecessary email from us please send note to firstname.lastname@example.org and we will take care of the issue.
Thank you for understanding!!!
