Is Training Plan Support extra now?

Yes.  It is an add-on.

From our user poll on the gold support, we changed this to include weekly log analysis as this is the one thing people overwhelmingly wanted.  We had to up the price and we made it a 'monthly' charge instead of all of it 6 months.

You can add online support on top of a silver or gold membership now.
