If you mean this forum, you can:
1.) Track a thread/discussion, which will send email notifications of replies.
2.) Use the RSS feed to watch for replies to a thread as well as new threads in the forum.
In the case of the latter, you can use the RSS reader of your choice. My Yahoo does glitch a bit too often, but there are many others to choose from and most browsers offer RSS support to some degree.
Hope this helps,
I have tried several times to subscribe via My Yahoo RSS. Always get the same message. "There was a problem with this app."
As an alternative, can't I subscribe via eMail? If so, how? I do not see it on the page.
