I keep getting two menus with each command

Say you both Annabelle and Jane are your subs, and both are wearing the Signature HUD. Saying /1. will call up the HUD Menu of both subs.

Or, Annabelle is your sub, but you are a switch and you are also wearing the Signature HUD. Saying /1c will rez cuffs for both you and Annabelle.

You can use the first part of your sub’s first name (minimum 2 consecutive characters) as a prefix to target that sub:

Example

In order to target Annabelle only, you can say:

/1 an c (an are minimal 2 consecutive characters in Annabelle – this rezzes Annabelle’s Signature Cuffs) or /1 anna g-- (anna are characters in Annabelle – this detaches Annabelle’s Signature Gag)

Or better, you can just change your sub’s command channel to another number (e.g. say /1 Jane .channel 2 to use /2 to control Jane’s HUD)

So, you can:

say /2. to get Jane’s HUD Menu, say /1. to get Annabelle’s.
