Ah, nice idea but practicality has to contend with brand guidelines and the acceptability of acronyms (no shortening is allowed!)
I’m thinking of re-branding (potentially) to create a shorter name, but in any case it gets repetitive if you use it for everything, but removing it completely means you end up with emails not obviously linked to the community - either not encouraging repeat visits, or being accused of being misleading
