Dear All, Please accept my apology for the unnecessary posting on this list of a private email to Henry. The problem arose because of an error I made in the "reply to" details for the new email account I'm running: this field contained details of my company postal address rather than my email address. As Henry attempted to reply to my message, the ic.ac.uk mailserver took the word "ChemWeb" in my postal address to equate with the local discussion list :-0 Rob Boyett. chemweb: A list for Chemical Applications of the Internet. Archived as: http://www.lists.ic.ac.uk/hypermail/chemweb/ To unsubscribe, send to majordomo@ic.ac.uk the following message; unsubscribe chemweb List coordinator, Henry Rzepa (rzepa@ic.ac.uk)
