Today I became aware of a change Google implemented in February adding new requirements for e-mails to be delivered to Gmail users. Until tonight, we were not meeting some of these requirements. This was affecting new members trying to register with a Gmail account since they never got the confirmation e-mail delivered to them. This also would explain why you may not have been receiving private message e-mail notifications to your inbox.
Just wanted to let everyone know I've fixed this issue now, e-mails from STBB should be delivered moving forward without issue.
If anyone is still having trouble, please let me know in this thread and I will have a look.
ps: Thank you Joa for your help getting folks who were having trouble manually registered the past few months! Sorry to anyone who wasted time digging through spam, trying new e-mail accounts, etc etc during this time..
pps: Sign up for Proton Mail, it's way better than Gmail (fuck Google)
