[R] spam warning

[ivo_welch-Rstat@mailblocks.com]

hi chaps:  I just found out that this R post list is actively harvested 
by some spammers.  I used this account exclusively for r-help posts, 
and promptly received a nice email with links to nigeria, india, and 
china.  this is not a good thing.  can we obfuscate the email addresses 
of posters, so that at least automatic harvesting won't work?

sincerely,  /ivo welch
