if you just want the signature editor to be limited, then it's just profile

PHP Code:

<if condition="THIS_SCRIPT == 'profile'"> 
... signature related markup
<else>
... markup for the editor on all but signature
</if> 


if you want to exclude something from showing up on the sig editor, then you can also put this around it:

PHP Code:

<if condition="THIS_SCRIPT != 'profile'"> 
... markup for the editor on all but signature
</if> 


THIS_SCRIPT is set at the top of a php file, for private messages it's private, and so on... for the signature editor (profile.php?do=editsignature), it resolves to profile.

so without having tested this particularcode, I'm pretty sure it works as I stated, I did a similar conditional here: https://vborg.vbsupport.ru/showthread.php?t=71609

let me know if it works out, or not?
