Hi Raf,
I am not aware of examples for doing it, but it should not be difficult. You need a controller with new/create actions and a form with the fields you want to expose. You can take a look to UbiquoUserProfilesController in ubiquo_authentication, the idea is similar but it is used to do the complementary (existing users updating its own info).
If you finally go ahead and you want to share a tutorial for other users, we will be happy to add it to the guides.
Cheers,
Bernat
I would like to use Ubiquo as a front end to a self service portal -
are there any plugins or examples for - self registration using Ubiquo
