Thanks for a quick reply.
The reason for me doing this is actually just for ripping on a friend of mine. I wanted to detect if it was him writing in the chat, then change it to something stupid. I also made a retarded hero with his name, and a little "disco dance" trigger. I love messing with that guy.
Anyways, can you recomend a chat system? And how does it work? JASS?
Edit: +rep btw. Thanks again.
