My mentees in China have recently reported the blocking of messages to AuthorAID in both directions to and from China. This is obviously of general concern, since scientific freedom is involved. Fortunately direct e-mail to and from me remains open at these times. IHowever it makes the AuthorAID messages look a bit odd, since it can appear that a task has been completed before it has even been agreed, but that is preferable to failed communication. If AuthorAID can do anything to ensure messages are not blocked, this would be prefereable, especially if the situation escalates.
