I use the forums a lot and I am not sure if they are owned by ubuntu or not, but it would be nice to have common login for all the ubuntu services, that way in the future you could add to the list of services, eventually people could get emails at ubuntu, have some way to tie their email to their computer emails, add programs to allow them to go to another computer with web access and access their computer remotely securely.. but all these are just 'possibilities' the main idea is

not having to register at different sites for common related ubuntu services thanks
