Hi Peter,

It is not possible out of the box to automate course group membership based upon seminar enrolment presently.
Unfortunately I have not heard of anyone having made this as a customisation or plugin either.
There are however a lot of customisations and plugins out there, and perhaps someone in the community has already built this and can share here.

Kind regards
Sam Hemelryk

Hi Peter,

We've got a custom solution that's somewhat similar to your description, but also the other way around... 

What we've built is a modified version of Seminar Direct Enrolment, where the learner gets to choose between available groups - and where each group is related to a series of events (one event per seminar activity in the course). 

This way, when learners enrol to a course they choose a series of events (to which they sign up), and are simultaneously made members of that group. Probably this could also be used to only enrol/sign up to a single event, in order to be assigned to a group automatically. Not sure if it could be used for your purpose though.

Cheers,

Rickard
