Any way to ignore system messages in the chat screen?

Solution 1:

"Red" system text, like "inventory full", "already have unique item" or "item already being rolled for" cannot be ignored.

You can remove the nomral yellow system text like "You recieve X credits", you can also disable the "social center".

Its been a while since I palyed as preferred, but whenever you are near your cap, a small chunk of text floats into view below your chat box. This is called your social notification center, I believe, and all new messages (like group invites, flagship invites, tutorial updates and system alerts) do that click.

If disabled, that sound and those messages should be off.

Again, red text can't be turned off.
