Two free registrations with dirrerent levels

[x3000gold]

Hi all,

I am using 2 free registration with different levels as described in this thread:
viewtopic.php?f=4&t=934

Have 2 questions.

1. Is it possible to let the visitor upgrade themselves to the other level?

2. My visitor will be able to choose 3,6 or 12 month subscription. I have added custom filed (Select Menu ( drop-down )) Is it possible to let their account expire automatically or do I have to delete their account manually?
