Regarding the chemical naming, Latejami (and my Saweli) have been sort of waiting for a good solution to this problem. I've discussed it with Rick Morneau, and he in particular has asked for help from chemists (and other professionals) to help with the naming problem. The same holds for biological species naming, although he has a fairly clear idea of how to do that already, as discussed in his Reference Grammar. stevo </HTML>
