Discussion forum integration with WP Wishlist & aMember

Hi there,

I've been researching the best way to integrate an autoresponder and a discussion forum with wordpress in a membership site. I've narrowed my search down for a membership site system to WP Wishlist and aMember on the strength of what they say they can do on their website. Still, some things are not 100% clear.

The key things I want right now are (all through a single registration):
1. membership registration leads to content delivery via wordpress.
2. automatic optin to aWeber.
3. automatic registration with a discussion forum (prefer phpBB first, then vBulletin).
(later will be interested in affiliate sales and am using paypal payments.

----
Let's compare the two for each of the three needs above.

A. Wordpress Wishlist
1. yes, it's actually a built in plugin that integrates with the Wordpress dashboard and does a lot of cool things. That is it's MAIN great feature.
2. it will do opt-in to aWeber very well.
3. it will not do discussion board registration unless its to BBpress or simplepress. I prefer to use phpBB because people are used to it's simple look. These two forums look busy and small print = hard to read.

Question: Will phpBB or vBulletin accept an email or script from the overall registration that it can parse into its own registration? Anyone write one yet?

B. aMember
1. it says it has a wordpress plugin. But they are not specific as to how it plugs in. Does it give the same features as WP Wishlist?
2. currently they have problems opting in to aWeber. It appears to have been like this for a while. Does it work in any capacity or is aWeber out of the question?
3. they WILL go automatic registration with vBulletin well. How does it do with phpBB?

The purpose of this site I'm creating is to make a membership site based on community interaction and educational continuity programs.

Thank you! Your thoughts are appreciated.
