By using the SMTP extension, I have been able to get notifications and subscriptions working just fine . . . except for one detail. Only one "subscriber" to a page is receiving change notifications even when multiple users have subscribed to the page. The others receive nothing at all. Has anyone had a similar problem. If so, please help me to find a solution. I continue to be impressed with DokuWiki, and I am hoping to find a workable solution soon. Thanks in advance.
