We have Odoo setup now to create a project from SO's, with tasks in that project generated from appropriate services the customer is purchasing. This is a great way for them to be able to track the progress of their order via the portal, we've found.
However, it seems we have to manually add the customer as a follower to the project once it's created. The closest to a resolution I've found was a feature request for v7: https://bugs.launchpad.net/openobject-addons/+bug/1099181
I still can't find a way to do it in v9c. Suggestions?
