Anyone know of a plugin with a simple trigger response function?
What I need is for this to happen:

Person says:
!SEND!
Me Sends Files: Current song.

I have BK Winamp Ext so (!SEND) sends the current song, I just need a trigger/response function for

!SEND! to (!SEND)...basically.
This has got to have been done, surley?

Can anyone help.

Thanks in advance.

ps. apologises for inelligent english.
