1. Does Gossamer mail have a stable payment system and if it does, does it include Authorize.net?

Also, if a member registers and pays, does the admin have to physically update that members info or is it automated when the payment is approved?

2. Does it work with the latest release of VBulletin (VB3)? This was a major upgrade so I need to know for sure.

3. I see 2 different POP mail plugins. One is for free (Auth_POP3) and the other is $500 (Pop_Server). My first thought is "you get what you pay for". However Gossamer is offering (essentially authorizing) the free one so I would think it would work fine. Can anyone please let me know?

Thanks!
