Can I block (General Window) Spell Messages.

[Ualaa]

I've added this to may pally tanking macro:
/script UIErrorsFrame:Hide();
/script UIErrorsFrame:Clear();
/script UIErrorsFrame:Show();

It has removed the red text in the middle of the screen, which says "spell is not ready" or "you cannot attack that target".

However, my general window is spammed with that information. I don't see an option in the filters to turn it off. Is there a way to turn this off or disable the message?

That is probably Jamba. In COMMS section, first checkbox should turn it off. If you want it but not see it, you can make a new window and then about 3-5th item down is a box to type in which channel to put that info in. Just do /join (Part of name)Jamba, like /join ElectJamba and then send that info to that channel and only put that channel in a new window. That is totally not needed, but just for info. Hope that helps.

Basically I want to be able to see Jamba quest update messages.
For example.

Vysha 1/5
Tessa 1/5
Arista 1/5
Judsea 1/5

I don't want, my spammed tanking macro to push that information out of the window with:
"That spell is not ready yet" x22 lines.

The updates for quests via Jamba are going to the general chat window on the current master toon.
The spam messages are only from the current toon, not the others.
I'm getting...

Judsea - Spell is not ready
Judsea - Spell is not ready.

Not getting spell is not ready for a spacegirl.

If I go onto the space girl screen and spam keys there (after promoting her to master)..
I get her spell is not ready information, but not that for the pally.

I suppose I can check by disabling jamba, if the spell is not ready info is part of Jamba.
