The Hidden Forest

I'm sure this has been covered but I am having trouble locating a solid topic on the forum about it.

I am currently 2 boxing and just using alt+tab.
What is a nice easy program to use for multi boxing especially if I wanted to add 1 or 2 more clients running?

are there any where I can issue a command from 1 client and have it sent to another or all of the other clients?

Take a look here

I'm sure you will find something interesting

winEQ2 is free. You have to register a basic account, but the program itself is free for the lite version, which is all you need for tabbing around and memory optimizations.

All other 3rd party software to make it easier to play should probably be discussed in it's own forum (link above me).
