Throughout this document, we provide some specific information that may be essential for observing with the VLA while it combines both ``old'' VLA antennas and retrofitted EVLA antennas. However, since this document is updated only (approximately) annually, astronomers are urged to consult http://www.vla.nrao.edu/astro/guides/evlareturn/ for the latest information, and follow the suggestions described therein. This is critical to the successful use of the VLA-EVLA baselines, which will encompass approximately half of the baselines of the operational VLA by late 2007 or early 2008.
