Seeing as not everyone has a 1/4 mile filled in could the memberlist be ordered by 1/4 times? That will give an indication of who has the quicker cars.
The memberlist default settings are currently set as 'joined date'.
This along with a few exceptions is noticeably the admin team & moderators etc heading the list.
I certainly think to add '1/4 mile times' to the existing seven sorting options albeit probably not as the default setting, is definitely a good idea.
