I make a post in a thread and the thread is blue-dotted. I then pal around on another sub-forum for about a week and return to find the thread has grown substantially. I would like to pick up where I left off, but don't remember where I was in the thread when I last read it.
Wouldn't it be keen to link the blue dot to your last post. This will serve as not only a signal to show you've posted there but also a bookmark. Interesting idea?
