Btw, if you know how to use git, you can update them just as easily. Just clone the repo, make a link in your .themes folder, and then all you need to do it occasionally pull for new changes.
But didn't make it easy for me. I ditched all places where I uploaded them and just link to github.
It keeps my motivation to work on them, as I only need to push the changes to github and that's it; don't need to bother zipping up and uploading anywhere.
Would be cool if the spices site incorporated github.
