Well, switching to Slack as the primary support channel didn’t work out either. Actually, I did work perfectly for the first couple of days. And then the spammers found the invite form and from there everything went downhills. I can’t restore the invite functionality for all invites have been used up and there’s no way to get them back. So I’ll close the Slack channel again and check out other options. For the time being there’s still email but given the amount of mail I receive daily due to my job there’s a good chance I’ll overlook a message or simply forget about it at the end of the day.
A side note to all those who complained that there is no email address to send support mail to: That’s not true, you for some or other reasons just didn’t try to simply use the “reply” function of your email client. Additional hint: There’s no “noreply” type mailbox here.
