Coming back to: Why a preprint's supplementary material is often the best part Replied, post #67 · Evidence › Preprints · 31 May 2026 · 25 likes I will take the caveat as seriously as the claim, which is the point of putting it there.

An appeal that succeeded, with the letter structure — the long version Replied, post #27 · Access › Insurance & coverage · 29 May 2026 · 24 likes Appeal deadlines are strict and are stated in the letter.
