How do I hide the notice?

1. On a computer, the one line of explanation for a section is on the band beside its section names, if it fits.
2. If it does not fit, it goes on its own shaded bar below. Only then does it have a cross.
3. Press the cross at the right of the bar. The list moves up into its place.
4. The notice stays hidden in that section the next time you open it, on this browser.
5. It comes back automatically when what it says changes. So a new warning, such as another late RFI, is never hidden by the one you closed.
6. When you sign out, every hidden notice comes back.
