Today I discovered the wonders of the change_availability script. Even though I sometimes feel like an old hand at SFX, this feature was new to me. It's a wonderful thing; I hope you get to know it sooner than I did.
I have neglected the new free full text targets for a while now and was facing the ugly, time-consuming task of activating them, their object portfolios, and getFullText services by hand. Locate the targets that use the getFullText service; figure out which targets have object portfolios; click, click, click endlessly through SFXAdmin to get everything activated. Ugh.
