[R] Statistical analysis of a large database

I thought that maybe authors of books on R should be allowed (encouraged ?) to announce availability/revisions of their books via the R-packages list?
For example I'd be very interested to have another look at Dr. Torgo's book when it becomes more complete and I'd appreciate a revision notice via the list.

Just a suggestion. Thanks, Vadim
