As nobody seems to answer my request, I simply post it again. Is there any reason why the r-help-mailinglist should not be converted to a newsgroup? These were the advantages of a newsgroup I mentioned earlier: -) you can easily search the archives -) the discussion is faster (I experience that the R-mailinglist has a lag of about 1 to 2 hours (not for everyone!!!).
