/Link in profile, can it be changed?

The photo shows my profile, and under my name is /iMumma which is a community I'm a leader of, but I'd rather have my Personal Blog /caleb be there. I can't for the life of me figure out how to changes this.. does anyone know how to change this?

I thought someone else would of posted this question, but I can't find any previous post via search about this... so apologises if this has already been addressed.
