Another post has disappeared 🙁
EDIT It may be related to adding complete web addresses. The post stayed when I shortened the addresses as below
Trying again
Some content which was free access previously is now members only. Is that a policy decision ?
eg
….videos/pushing-the-limits-using-commercial-spectrographs-2
….videos/using-low-resolution-spectroscopy-to-confirm-supernova-discoveries-2
which I have linked to on other forums
