I am looking for a Social Networking Platform (LAMP preferably) - Open
Source would be ideal, which will allow the user to see a specific
template once they login, dependant upon the domain they align
themselves to during sign-up.
The user chooses an email username, which is then attached to one of
200 domain names. This domain is branded and the user sees this once
they login through the main portal.
ps: as for assigning email addresses - I am open to taking advice
here too!! :)
