How to change users prefix from mcps to +OK or ecb?

[KiTTy]

Reason why:
There is one user that a fish encrypted bot won't respond to.
I noticed that any user that their text is prefixed 'ecb' or '+OK' bot will respond, but not those that have: mcps

Is this a simple setting to change in Mircryption?

Thank you very much!

fish doesn't understand mcps.
if you want to talk in a channel with people using fish, and you are using mircryption,
right click in the channel and tell mircryption to use the +OK prefix.

Thank you mouser I figured it out, was trying to get here fast enough to edit out post so you wouldn't see it haha
right click/mircryption/more commands/ 'change encryption prefix for channel to +OK (blowfish compatbile)'
