1. Do you also save the zipped files?
Nope. Saving them never seemed worth it IMO. I don't save my LOs' TIFFs either. But after Rae's issue, part of me wonders if I should save zips *and* TIFFs?
2. Do you typically use each kit to make just one page, or multiple uses?
Gosh, sometimes I feel lucky to use a kit once!
But some kits I use multiple times. I guess it just depends, but "once" is probably my average, and then "many times" for a select few kits that seem to have some items I consistently need.
3. Do you remove kits from your 'database' once they've been used as many times as preferred?
I remove kits that no longer speak to me. Recently I went through my EHDs and I got rid of basically anything pre-2008. Also, my most recent EHD doesn't have much pre-2014 DS stuff. I figure that stuff is on 4 other EHDs...it doesn't need to be added to this new EHD, ya know?
4. How do you handle kits that are retired/from retired designers?
I don't do anything to them; I scrap with them but I don't post them in galleries--or if it is a page I want to post online, I try to remember to add "(retired)" to the description in the gallery.
