Cynthia: Thanks for answering this question for John and checking into things. Even though I am the webmaster for the IGS website, it would be great to have some additional people that can answer questions. Perhaps we could add some additional names and email addresses to the webpage for different types of questions? Is Cy ok? . -- Diana Pederson Column: http://www.suite101.com/topics/page.cfm/262 Mail-lists: http://www.suite101.com/userfiles/553/maillists.html Business: http://www.tir.com/~enabling/index.html
