Ok, I know what would make the ultimate vedor connections now.  After using it for a while now 90% of the orders go off without a hitch, the other 10% have one of the following problems:

1) Email is not reliable, it doesn't get delivered fast enough or spam blockers pick it up.

2) When users come back for updates, they don't remember their logins because it's typically not the login that they normally use.  The user John Doe will use a login 'sillyjohn', not 'jdoe'.

So I reccomend the following:  Collect the sales like VC normally does,  Users then create their own accounts with the login name they are used to.  Then there is a module that allows users to claim their order.  They can paste their order ID and mabye zip code or email for extra security, then that sale gets associated to that user, and the normal VC processing occurs (assigning roles).

Any thoughts?

Thanks,

Mike
