I am working on a site for a club where they want members to be able to register themselves and at the end of the calendar year their account expires. The self registration is working fine. I have the expire date set for 12 months - but what I really need is to have it automatically expire at midnight on the last day of December of the current year. I really don't want to have to manually set this for each user. Is there a way to have this as the default when created or a page/command used by an administrator that would blanket set everyone's Expire Date to a specific date & time? Has anyone developed something along these lines?

Thanks in advance

The only thing I can think of is using a UDT that will set their expiry date when the user is created. The UDT would be triggered by the built-in Events system (under Extensions) when a user is created via FEU. There might be PHP examples in the forum to get you started.
