I would really like the option of changing the user title to be based on the date/time of registration rather than total number of posts.
I'm sure many admins here don't like that users will just post or spam to up their post count.
This way, my long time users and lurkers, won't have silly titles like "newbie" due to a low post count if they've actually been registered for years.
Similarly, "newbies" will remain as a newbie for however long it is defined, and can't do anything to change the fact that they're, well, new to the community.
I'm actually going to look into doing a hack for this myself, but just thought I'd throw it out there to see if there are any other like-minded admins that would prefer this paradigm-shift of sorts for user titles.
