Query: A Coordinated Radio Afterglow Program   We describe a ground-based effort to find and study afterglows at centimeter
and millimeter wavelengths. We have observed all well-localized gamma-ray
bursts in the Northern and Southern sky since BeppoSAX first started providing
rapid positions in early 1997. Of the 23 GRBs for which X-ray afterglows have
been detected, 10 have optical afterglows and 9 have radio afterglows. A
growing number of GRBs have both X-ray and radio afterglows but lack a
corresponding optical afterglow.
