[R] Discussion: Spam on R-help

[Christian Hennig]

Hi Ted,

the R-help list is maintained by Martin Maechler, ETH Zurich, 
who is not at work at the moment. We had various computer problems at the
ETH in the last week. It may be that the spam filter broke down somehow and
Martin is not here to fix it. I think the reason for the lots of spam are
temporary technical problems and I hope we will have a "filtered" mailing
list again in one or two weeks.
