Is there any way?

[hexcorp]

I have a Magento store where I am selling online classes. My Magento is integrated with vBulletin using AITOCs integration module. Depending on which class a customer buys, I would like them to either to be added to a join-able group for that class or add a secondary user-group to their account.

If this is not possible, is there a way for vBulletin to read an outputted file with emails and place any user with the same email into a specified class or join-able user-group?

Any way around this obstacle would be appreciated! Thank you!
