Registration side wide- universe wide

[Johnboy]

We would like to include MP Multiside, but before we do this, we have
some more detailed questions:
Assuming someone would register an Acc on the mothersite, will this
registration be handed over to the childrensites as well?

Assuming this is not the case, is it possible to give the user of a
childsite the possibility to register himself to the mothersite along
with it?

Assuming a registration on the mothersite does handle the registration
to the sistersites, can the childsite admin exclude his network from
this?

Hi Johnboy,

Currently every elgg subsite is like a separate elgg install, with
separate databases and users, but sharing the same source code.

Users on a subsite can't log in by default to the supersite (which is
a good thing, as the super site is really for admin only). Equally
users on one subsite can not by default log into another sub site.

I think the correct way to solve the latter issue is through
federalisation - solve that and you'd be able to log into any site on
the network, multisite subsite or separate elgg install.

The pieces are there (Oauth, OpenID, Activity streams, etc) but so far
I've not had a chance to really get stuck into it - this could be
something for the wider elgg community!
