Hi,
After new investigation, Google + do not allow automatic post, we have to candidate for their API, that what we've done, twice.
There's an illegal way by using a tird party account, unfortunately if Google detect it, your account will be closed.
The new version will include LinkedIn enterprise post and vkontakte too. The version 2.0 is already downladable and will be annouced in a newsletter soon.
Regards,
