I figured people who use multiple PC's or wanted something for their work/travel/whatever computer could use some freeware. Check out sport tracks if you haven't already. Theres a power analysis plugin that does TSS and NP and a few other things. The program isn't hard to use and I have to say that I do like the setup.
I think I might start using it as a 'training diary' in addition to WKO+.
