HelpHelp in Coding DLL for KRelay

Hi guys
I want to run a mule client that trades to other players to sell itens.
I just need to know how to send comands via /tell from my main account to the mule, contening instructions like, who to ask trade, item to sell and item to accept has payment.

So, all i need to know is how to recognise a /tell in the chat, and from who it came from.

Anyone can help with this?

First of all you need to understand packet system, you can start with reading this mpgh(dot)net/forum/showthread.php?t=779931
same thing with k relay. Then read the documentation github(dot)com/TheKronks/K_Relay_Plugin_Documentation
and dont forget to check samples. ( sorry i cant post links )
