Questions about Vbulletin 4
 

I hope this is the right forum.

I'm currently a Jelsoft customer since I have a forum that's still active* but lost interest in vBulletin after 3.8 was released because Jelsoft has turned it into a MySpace clone with those weird profile pages* etc.

A few questions about vBulletin 4:

1. Does it support PostgreSQL?
2. Does it integrate well with an existing authentication system (single sign-on)? vB's authentication system might be super awesome* but mine is super awesomer. :)
3. Is it well coded (PHP5-only* E_STRICT = no warnings* etc.)?

The first point would be a nice to have. The second and third points decide whether I stay a Jelsoft customer after my license expires at the end of the year.

One of the things I have always hated about vBulletin -- and I am not the only one -- was how painful it was to integrate with one's own code. I honestly hope that improvements have been made in that area.
