Hi. I am also a great fan of this mod. I made a new version of the PlayerDialogs mod, based on croxxxs version with the /reload_dialogs command. My version of the mod adds also a command, called /list_dialogs. It shows a player with the privilege "list_dialogs" all available dialogs. For example if the server has the dialogs /rules and /info, it will show you:
List of available dialogs:
/rules
/info

I think this version is really useful
