I don't know about all of you but I tend to go to the memberlist mostly when multiple new people sign up, just to see who has signed up and to read their profiles (if it's just one, I check the newest member link). I have always found it somewhat inconvenient that the memberlist always comes up with the people who have signed up first on top. I then have to click the last page link or sort in reverse order. I hope I'm not alone on this because I just changed things.
Now, when you go to the memberlist, the sort has been changed from joined date, ascending to joined date, descending. This will mean that the newest members will always been on the top of the list.
If you don't like this or if you have a suggestion for another default sort, feel free to suggest it and I'll consider the suggestions. In the meantime, I hope you will find that this is more convenient when looking up new members.
