G'day perlfan,

If you are looking for some function whereby you flag a thread and get an email (or other notification) whenever that thread changes, that's not something that you "somehow missed all these eons" [or even in the last 18 years since you registered :-) ]: such functionality does not exist on this site.

When you log in, you will get a notification if anyone has replied to a node you wrote. You can also use "Newest Nodes" and "Recently Active Threads".

I log in nearly every day; sometimes more than once: "Newest Nodes" generally suffices for my needs. I use "Super Search" (often with author=kcott) to find older nodes. Occasionally, I bookmark a node if I think it has information that might be useful at some future date.
