User Passwords and Email Domain/Confirmation

[Doughboy1978]

Hi,

Before i take the giant leap of buying vbulletin could someone please answer the questions below.

1. Can you restrict registrations to a specific e-mail domain?
2. Can you force users to change their password after a period of time e.g. 60 days?
3. As a user changes their password, can their account be set to inactive until they follow a re-activation link from an e-mail?

Other forum providers, who shall remain nameless, can do the first two of these but seem a bit unwilling to even consider the third question. If i can be guaranteed on all three then i will buy a licence and use vbulletin.

Thanks in advance
