Thanks for mentioning me and Kayla's class, Adrianka and Lynnette! I totally get not wanting to tag for the time element, seriously! LOL When I finally decided to take the plunge after looking at Kayla's class, it took me about six days (averaging about 3-4 hours per day) to tag my 160GB stash (about 1500 previews).
For myself I just tagged my previews. Which means that generally I don't break alphas out of their kits. I think I only tagged those alphas that had their own previews--if they didn't, whoopsie, lol. I also only tagged alpha packs I'd bought.
