This may be very simple,, but can I turn off the output echo (or whatever it is) and if so how?

click echo on triggers.. off under prefrences

Cheers, also how would I gag a message on the second time it appears.

For example clotting, how would I get:

1160h, 1100m, 1040e, 0p ex-
You do not bleed my friend.
1160h, 1100m, 1040e, 0p ex-
You do not bleed my friend.
1160h, 1100m, 1040e, 0p ex-
You do not bleed my friend.
1160h, 1100m, 1040e, 0p ex-

To be:

1160h, 1100m, 1040e, 0p ex-
You do not bleed my friend.
1160h, 1100m, 1040e, 0p ex-

Whilst still clotting three times?

my guess...
Triggger: You do not bleed my friend.
Command: NotBleeding=1
......... #if {notBleeding=1} {#gag}

Trigger: You bleed %1 (or whatever the line is)
Command: Notbleeding=0

Make sure you put an @ in front of your variables when referencing them. Also, if you want to see the first and not the rest, make sure you set your variable after you check the condition.
