Dear Dr Hoogenboom Thanks for adding me back to the DSSAT list. I sent a "forward" message and a "Confirm DSSAT" message, the latter to DSSAT rather than listserv. I apologize for the error - I know better. One of the two messages worked, as I had a response to that effect. Thanks. Sorry to cause extra effort. T.T.
