Your Credit Card please...

Training at CTP has abruptly ceased to be free.

I have progressed through all of the CTP site "Welcome" modules and the "how to" CTP site Tutorials. Next came the new CTPtalk modules, the Trafficwave and the TW-affiliate modules. 

I doggedly worked my way through the finer points of "Click", then "Track" before reaching the middle of the "Profit" modules  when tout à coup, I abruptly "hit the wall".

SIGH...the Yellow Brick Road ran into a toll-gate.

Is time to upgrade or I can't go any further. (soft crying noises)
