Query: Can light Goldstone boson loops counter the `S-argument' against
  Technicolor?   We examine the oblique correction phenomenology of one-family Technicolor
with light pseudo-Goldstone bosons. From loop calculations based on a gauged
chiral lagrangian for Technicolor, we are lead to conclude that even though
loops with light Goldstone bosons give a negative contribution to $S$ measured
at the $Z$-pole, this effect is not sufficiently large to unambiguously counter
the `S-argument' against one-family Technicolor. This result cannot be guessed
\apriori, but must be explicitly calculated. Our analysis entails an extended
version of the $STU$ oblique parametrization of Peskin and Takeuchi. In
principle, this extended formalism ($STUVWX$) must be used when there are light
new particles in loops.
