A simple plugin that prints to the chatbox and console all players that have the flags specified. If a player doesn't have ALL the flags you specify, it will still print any other matches it finds.
Command is /FindAllFlags
Comment with any problems you come across, only tested this with one person (myself) so not sure yet how it'll act with more than that. Shouldn't be any problems though.
If you are adding me on steam to discuss problems with this or another plugin of mine, be sure to mention either here or on my profile page before you do so I know you're not some random.
