Custom User Titles

[pyrrhic]

I see some users with custom user titles, and since I couldn't find any information about how to obtain one through the search engine, here goes:

Are custom user titles still availible? If they are, how long do you need to be registered nd how many posts do you need to have for that option to be activated in the user profile?

*doh*, I just tossed in "custom user" in the search engine and nothing came up; my bad.
