The board puts the meaningful thread navigation variables in the URL, so you can just bookmark a thread if you don't want to lose it, so if you wanted to remember where a thread was -
say, the one where my screen name is discussed - you can just bookmark it like normal and have it saved if you ever need it again. I've done this with
this thread,
the roleplay thread, and
the jokes and riddles thread, to name three, so I don't need to go searching every time I want to read them over.
