Virtuemart default shopper group

When users register through the CB registration process on my website, they are visible in virtuemart.
But there is no default shopper group assigned.

I had a look at the tables an noticed that no entry was made in the jos_vm_shopper_vendor_xref for the new registered users.

How can I have my CB registered users assigned to a default shopper group in VM (I dow want them to be shoppers as well, once they registered on the site).

I do have CB Subs installed but not enabled yet.... maybe this has something to do with it?

Users are not actually created in virtuemart without the assistance of an integration. If using CBSubs then CBSubs VirtueMart can do this for you assuming the user is subscribing to a plan that is utilizing this plugin. Otherwise incubator project available to professional subscribers CB VirtueMart can accomplish synchronization at various configurable triggers such as after login.

Incubator VM project looks nice, and the right tool.

When running bot the incubator and cb subs, won't they bite each other? (my cb subs is not yet active, but for future sake).

Does the VM incubator plugin do something without creating triggers? (it looks not to me)

No, they won't conflict.

Incubator project synchronizes users based off the triggers you've specified it to such as after login. It is a guided setup (via jQuery) so is relatively straight forward to configure.

Is there a way to manually trigger the triggers created? I have one set up as AfterUserConfirmation, and want to have this triggered to see if it works as expected.

Can I set a default value for a field to be synced, instead of specifying a field?

Confirm a user, easiest one to test is After Login.

No, it transfers a fields value to VM. Suppose you could specify a field you've defined by editing the user and that value would then of course transfer.
