I don't use the mark as read option

however I'd use a "mark this thread as unread" feature. Right now I do not dwelve into a thread if I can't read it whole at once, because if I read only a part, the next time I visit the forums I see it marked as read and don't know there's more I might look at.
Well, actually it isn't that much of a need because I am just fine with bookmarking threads I'd like to read more
