Do I use SSO if I want to add more Q&A sites that shares the same user table?

Question

I have 1 Q&A site running and want to add more Q&A sites (not all at same time), what is the best way of doing this?

Same problem here. It is appreciated to any help.
I tried to use cURL to force it share session ID between two domains but no luck.

No, you do not need SSO, that is only when you want to integrate with an external user base (e.g. Wordpress, a forum or your own user system).

For multiple Q2A sites you can simple set an option on the second site after you have set it up. See http://www.question2answer.org/qa/5622/how-does-the-multiple-q2a-sites-work-in-1-4

Thanks DisgruntledGoat. Though I have problems when I have one site set up and running, then want to add another site later.

I know you can set up both sites at once but I may continue to link more sites later. The problem is when I set up a 2nd site after the 1st site is running and already has activity - it overwrites information like usernames, etc.

Any help is appreciated - thanks!

Not sure what you are doing to get it overwriting usernames... Make sure you are setting up the second site with a different prefix such as qa2_, then set users prefix to the one for the first site: define('QA_MYSQL_USERS_PREFIX', 'qa_');

I had set up site 1 and it's running with some activity already, then set up site 2. It seems I have to set up the sites together as Gideon says here: http://www.question2answer.org/qa/13857/2-q%26a-sites-error-in-merging-users?show=13909#a13909

I wondered if there was any way around having to set up all the sites at the same time before they go live - because I will add more sites eventually over time.

Thank you.
