Looks to me as if it is custom coded. There use to be a mod a few years ago called "micromembers", but it was not on the vbulletin.org site. I cannot find reference to it anymore on the web. Unless someone else knows of something you might have to alter existing code or post in the "request unpaid" or "request paid" forums.

Sorry, I could not be of more help.
