This plugin is essentially an alternative to amx_psay. I thought of it because one day I was trying to have a conversation with a player through amx_psay and was not the easiest because I had to go to console many times which was annoying. Another thing that I did not like about amx_psay was that when you are responding to some one who uses say_team @message then other admins don't see the reply.
How it works:
a2p_target <playername> - set who your target is going to be
a2p_message <message> - send your message to your target
* These commands are intended to be used with binds using messagemode.
Examples:
Threaded Mode
