Now to start this off you need to Go to Connection --> Quick Connect name it "chat" and as the IP put 0.0.0.0 so it doesn't actually connect. Now with that new world go to Game --> Configure --> Output and change the "Wrap output at column number" to how much you want to see
I have found 84 can hold it very well. Also check Auto-Wrap to Window size on the left hand side.

Now that that is ready open your actual world and install the below plugins.

To do that you will click and save these files as .xml and save them in Mushclient-worlds-plugins

Then go into your world and go to File-Plugins and look through them all and upload chat, and OmitBlankLines

Now all chat should be moved to that new window.

EDIT: I have changed the chat plugin to now have a space.... for all that was wondering. Also any comment or questions just ask.

EDIT: Apparently the wrong ones got uploaded, so here are the new ones

I haven't been able to get the above working. So here is my version.

The same setup directions apply:

1. Go to Connection --> Quick Connect
2. Name it "chat
3. For IP put 0.0.0.0
4. Now with that new world go to Game --> Configure --> Output
5. Change the "Wrap output at column number" to how much you want to see
6. Also check Auto-Wrap to Window size on the left hand side.

When you load the plugin, make sure you load it in your Lusternia world.

The plugin should take care of tells, says, and aethers. Let me know if you find any bugs/strange occurrences.
