Hello, I use Jomsocial and Virtuemart on a 3.8 Joomla website.
I would like to automaticaly map and sync Virtuemart fields for billing and shipment informations with custom fields created in Jomsocial.
When a user register in Jomsocial, he will directly enter all those informations in Jomsocial registration page, so when he will put an order in Virtuemart, all those fields will be already updated and the user won't need to fill it a second time in checkout.
If those data have changed between registration and order, if user update his informations in Virtuemart, it should be updated in Jomsocial too.
If the user modify his billing address or shipment address in Jomsocial, it should be updated in Virtuemart too.
Need to be done without core changes in Virtumart neither in Jomsocial or Joomla.
