There was a problem with the registration after the last platform update. Some new users could not complete the registration process. The problem was fixed. Should you be affected, please resend the confirmation email for your incomplete account and you can use it then normally.
E-Mails to Yahoo accounts:
Yahoo server are currently blocking emails from this platform. If possible, please use an email address from
another provider. Should you already have an account, you can change your email address in the account settings.
Unfortunately, this problem occurs over and over with different large email providers.
They protect their users from spam, but sometimes they overact and block benign small servers.
I'm already using for this platform a service which monitors these problems and tries to resolve them quickly.
But more I cannot do, unfortunately.
Should you don't want to change your account email here: It will work again in a few... hours or weeks.
The problem occurs now also with Hotmail addresses.
I got some anonymous messages that the message system would not work anymore.
I could not find any problem.
Should you have problems with sending messages to other users, please contact me
via the anonymous (!) contact form at the end of each page or via email
– and don't forget to mention your username and email.
Problem solved. A security technique overreacted which caused that a few messages were falsely classified
as an attack and blocked. Many thanks to all of you who send me messages so that I could resolve this issue!
