I don't know if ours works the same as over on RV.net, I don't go there much and am not familiar with how they are set up.
With ours, if you turn notifications on for any of the forums or threads as indicated above, an email will be forwarded to you at the email address you indicated in your profile. From that email you can click on clickable links to take you directly to the thread or forum. The email will contain the full text of the message, often I'll just read the content of the email, skipping the link to the site.
Good luck with it; I use it all the time and receive 30-40 notifications daily.
Another feature you may be interested in is the House icons immediately to the left of each forum. If the icon is lit up (colored), that means there has been a new post made in that forum since you last logged off.
Another feature is to click on Find>>New Since your Last Visit. A list of all posts made since you logged off will be available and you can skim down through them looking for what you want.
