Sorry to pester as I learn but i am confused about the following statement I read in the docs:

Docs say

allowed_shared_usernames – set this to '1' if you want to disable the feature where new logins
takes over an existing session for that username, if it exists; this allows people to share
usernames

1 disables a feature of people using anothers session by loging in with the same name?  I am really confused here could you please explain in clearer english what this means?

By default each username gets one session, and one session is tied to one IP address. The advantage to the default approach is that session IDs persist for a particular user even if they've closed and reopened the browser. The disadvantage to the default approach is that if people share a username, they end up logging each other out.

I'm also naturally a joined-up thinker, so I always express my thoughts in combined business and technical terms. I recognise not everyone likes that, don't let my Vulcan-thinking stop you enjoying ocPortal on fun personal projects.

Just to be completely clear, when you are saying username you are really saying login account correct? Or are you implying there could be 2 accounts with the same username?

So basically if I login at home do some stuff head to work the same session is available when I login from work and also when I get back home if I have enabled this feature?

Yes username=account.

No, this is the default behaviour. The session is reactivated when you log back in (either manually, or via the login cookies).
The hidden option reverses it, creates a new session for each login.

allowed_shared_usernames - By default each username/account gets one session, and one session is tied to one IP address. The advantage to the default approach is that session IDs persist for a particular account even if they've closed and reopened the browser. The disadvantage to the default approach is that if people share a username/account, they end up logging each other out. Set this '1' to allow usernames/accounts to be shared, by no longer persisting session IDs.

Thanks ok makes clearer sense to me now. Sometimes after reading so much the way things are worded can cause a brain fart (well at least for me lol)  and look as if it's written in a foriegn language or something.  :$
