in reply to Give Maintainer Permissions to delete their own nodes?

Perhaps, in addition to the much and often requested "empty post" logic check when submitting, it (the program) could also check for duplicate posts, by seeing if the content has changed at all from the previous post in the thread:

$Post = &MonkHasSubmittedPost; length($Post) or &ErrorScreen("Empty posts not allowed!"); $Post eq $PrevPost and &ErrorScreen("Duplicate post rejected");

You get the idea....
