To be honest, I trained our people in-house. After test-driving Wildfire & getting hold of the online help, it was fairly easy for me to write a few worksheets showing the new functions, etc... Each user had an intensive 1-day intro to WF.
For 50 users it made economic sense to do the training ourselves.
You're forgetting the main reason PTC came out with WF in the first place and that was to attract new users (especially from solidworks). It sure seems like there's a lot of new users lately posting to this site.
