Dear R-devel readers, a machine has been set up that provides services for non-Windows users to check their source packages under Windows and compile a Windows binary without having to go the CRAN way. This is intended to a) provide the service for users who do not (yet) want to submit a package to CRAN and b) allow users to test and check their packages before finally uploading to CRAN. In particular those who asked me from time to time to look at their package can just use this automated service. For details about the service and how to use it, please read http://129.217.207.166/index.htm As stated on that page, you are using this service on your own risk and we do not guarantee privacy nor confidentiality. Thanks for comments and suggestions to Torsten Hothorn, Duncan Murdoch, Paul Murrell, Brian Ripley and Simon Urbanek. Thanks to the University of Dortmund for funding the machine, electricity, space and bandwidth. Best, Uwe Ligges
