The old format scanned every single file and produced a list of titles, not sorted or indexed. I liked it but it could not handle the sheer number of posts (it had to search every topic EACH time it was called) so was very hard on the system.
the Active Topics is quite good, it is a 'real' 24 hours of tech (I wouldn't upgrade until it showed a full 24hrs, the old one started at midnight each day).
It's almost the same thing, the old what's new showed just the titles, well, so does this one, but it also gives a bit of info on the last post for those of us who can't remember if we read it or not.
It's also sorted by time, so really, it's the same thing, only better.
Thanks for the kind comments on the old way, I'm kinda proud of that hacked script, we were the only ones who had it.
