ScriptNukePGP

From 40tude Dialog Wiki

This script removes PGP signatures when reading newsgroup posts. It is based on scripts by Matija and Marcus, with help from Jarrod. Thank you!

Updated 6 July 2005 to add changes by Miroslav Sabljic to better handle GnuPG sigs as well. Thank you!

Tested on v2.0.15.1. Paste the script into the OnBeforeSavingMessage event, compile and save.
