Registration issues for users from China
At the moment, we have observed users connecting from China can't register on the journal site, getting an error stating "You must complete the validation check used to prevent spam submissions."
We are aware of the problem, which is due to the chinese state firewall, preventing connections to certain Google servers, where the CAPTCHA system is hosted.
The problem will be resolved as soon as we will perform the site upgrade to the new version, which is scheduled soon.
In the meantime, users from China are encouraged to send an email to the email@example.com, containing their details, so we can manually add you to the site.
