Once I up or down-vote a post, I never see it again, unless someone responds to something I wrote. If there's something I want to check later, I have to Save it.
If I respond to a post or comment, and then that gets edited, I'm pretty sure I don't get notified. And since I've already up-voted it, I'll never see it again (unless I Save it and remember to check it later).
If a post is more than a day old, and the info you're editing is important, make a new post. Reference the first post if necessary.

The Count of Monte Cristo is excellent. No movie has done it justice. No movie has come close to doing it justice.
The Three Musketeers Saga is very, very long, and very, very inconsistent in quality.
Moby Dick is really good. Also makes for a good movie, because there's a lot of stuff about whaling that nobody cares about anymore.
Start with those, I expect a report when you return, along with an essay about what you did during the summer.
