Hugo has Porblems signing up @matthias can you help?
Hugo used a Gmail address to sign up, and at the moment the forum has issues delivering e-mails to these (and we’re still figuring these out …).
For now I have manually activated his account, so he should be able to sign in. A password reset etc. will not work yet, as it relies on e-mail functionality.
Also, you probably want to assign him to relevant groups (here).
Figured it out. It was about an accidentally deleted SPF record. After DNS propagation time of ca. 8 hours, e-mail deliverability to all addresses should be back to normal.
