Reusing deleted sites in Buddypress

SOS – Stuck on Stupid:

I forget that I have to create new blogs via the new group creation process and will create the new site on the backend. Well I need to use a particular naming format for all blogs and when attempting to use the same name I get saying the site is in use and no longer available. My initial guess is to remove this from the DB possibly using phpMyAdmin. Can someone confirm and guide me on where to do this?

Any responses appreciated.
