Finally found a tagging plugin I can use. It’s modestly named the Ultimate Tag Warrior, and K2 has built in support for it so that I didn’t even have to do anything other than plug it in and turn it on. Best feature: entering comma separated values on the “write” page—my fingers just won’t do the dash or underscore thing. Check out the tag cloud near the bottom of the Archives page to see what we’ve been chatting about lately. I’ve gone through most of two months of old posts so far, and it’s usefulness will only improve over time.
Your in the same boat as me, I’ve got something like 1300 old posts to got and retro tag, I just cant find the time or motivations though
