Rules For Dibbing
The dibbing window will be open for the weekend prior to the start of a new round. Thus, if round A1 ends on January 29 at 17:00 US Eastern Time, the dibbing window is open from 17:01 until 08:00 on Monday, February 1, when round B1 starts.
To dib a particular entry, you must be the first person to edit that entry in that time window, adding your name and timestamp (ie, type --~~~~). Early dibs will be punished by mocking.
