I use a single DB for two Q&A sites :
I tried (as explained in qa_config.php) sharing same users with prefixing :
user tables with : qausers_
tables for qa1.mysite.com with qa1_
tables for qa2.mysite.com with qa2_
I created qa1.mysite.com before qa2.mysite.com
When i create qa2.mysite.com, i expected seeing all users already created from qa1.mysite.com.
However, the page qa2.mysite.com/users gives only superadmin and admins users, not regular users.
What did i miss ?
