Mary, thanks for your help. We do need guest access for our parents. I looked at the forum thread and read it pretty carefully, trying some of the solutions, none seemed to work (but some go back to pre-2.0 versions. One of the things I checked on was whether there is a guest account in myphpadmin. There is an admin account but no guest account there. It is unclear to me whether there should be one or not because it is a "built in" account. But it seems like there should be one. Should I one? I'm not sure how I would set up the account, such as what to use for the email address. Is there some who has moodle with a functioning guest account where they could check in myphpadmin for how the guest account is set up?
Thanks for any help you can give me!
