The BFKL equation resums large logarithms that dominate the cross section for this process. After a brief overview of analytic BFKL resummation and its experimental status, we report on a Monte Carlo method for solving the BFKL equation that allows kinematic constraints to be taken into account. We discuss results for $e^+e^-$ collisions using both fixed-order QCD and the BFKL approach. We conclude with some brief comments on the status of NLL calculations.5 pages including 3 figures, Latex, uses epsfig,ws-p10x7.cls; talk presented at the XXXth International Conference on High Energy Physics, Osaka, Japan, July 27 -- August 2, 2000High Energy Physics - Phenomenologytext
