[Gretl-users] The RVNR (rank von-Neumann ratio) package

Dear fellow gretl users, does anybody use the contributed function package "RVNR" (description: Rank Von Neumann Ratio) ? This is a non-parametric test for autocorrelation. It has some (minor) problems and I cannot reach the author Guillermo Verduzco Bustos, guillermo.verduzco(a)alumnos.cide.edu. If it really is abandoned, would anybody like to become the new package maintainer? It has only 55 lines of code, probably less after some streamlining. Thanks, Sven (one of the moderators / coordinators of the contributed packages)
