Does messenger plus have an auto reply.
eg a person sends a message and your messenger replys back to them with a message.

Or if one of your contacts send a key word it sends particular message back

If it does where abouts do I go to find it

You can if you use personalized status (f.e to let them know where you are etc.). When you put your status to away you can set it in the screen you get

Edit: yw

Another feature you might find handy:
The come-back message (rightclick contact > plus extras > set come-back message..don't forget to check that lil checkbox on top left to set it). If a contact goes offline and you leave your comp (staying signed in) and you wanted to say something to that specific contact, you can put that in the come-back message. If that person signs in again he/she will get that message automaticly (providing you are still logged in)

Thanks sunshine, Ill look into that

Thanks again sunshine.

What I want to do is

I run a gamming clan and I want just the memebers to be able to trigger a bot or something that can reply to them of what a game server settings are and when the next match is on  etc.

Currently, the only way to do this is by creating a Messenger Plus! plugin (which you can do easily if you know some VB or some C++).
