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 --- ivo welch professor of finance and economics brown / nber / yale
