\\  {\em A precision of $10^{-6}$ on $\sin^2\theta_W^{eff}$ is a reasonable goal for the measurement of the leptonic weak mixing angle at TLEP}  An electroweak correction of great interest is the vertex correction to the $b$ partial width, which affects $\Gamma_Z$, $R_\ell, the peak hadronic cross-section and, most sensitively,  $R_b \equiv \frac{\Gamma_b}{\Gamma_{had}}$ \frac{\Gamma_b}{\Gamma_{had}}$. $R_b$ was measured at LEP and SPC by tagging $b\bar{b}$
