I guess all we can do is be patient... take your time, but hurry up! (I learned a Latin phrase to that effect... what was it? Festina lente, sed festina?)
Yep, that's it. I learned it off by heart when it was first posted, and I have used it almost constantly ever since, so it stuck very nicely.
This is what I have been doing. Note the posts from today, then look at the timestamp and read the threads with timestamps later than my last visit to the forum.
I usually look at the last poster in a thread. Most of the posts above the top thread with me as the most-recent-poster are going to be new; some aren't, but it at least keeps me from searching the entire forum...that can be time consuming.
