Okay, I've noticed some threads on Letsrun disappear occasionally and then come back. Not because they're deleted, I think there must be either a bug in database code or the presentation code.
For instance, the last post on this thread:
http://www.letsrun.com/forum/flat_read.php?thread=3814281
was at 9:17 AM. However, it is nowhere to be found on the list of threads. At the bottom of page 1, the last thread has a time of 9:50 AM, and on the next page, the top post starts at 9:08 AM. So what became of the threads in between?
I'm not sure how long that thread will remain hidden -- it will probably become visible again soon. Has anyone else noticed this?
