A couple of days ago I switched my options for the adsm-l list to receive the index in html format. When I click on an index item link, I get the message: 'Unknown/Unsupported option' after a bit of a pause. I sent some mail to the list owner(s) yesterday but so far have not received a reply, so I thought I would check with the list to see if anyone else is using this option. I have a similar option set for the ibm-main list and that works fine. My browser is IE V5. Thanks for any suggestions.
