Yes - it’s easy to run multiple copies of Jamroom on the same server. The easiest method is if you have access to another MySQL database, you can simply place the new copy of Jamroom into a unique folder on your website, then when running the “install.php” script, make sure you specify the new MySQL database name. If you only have access to 1 MySQL database, you can install another copy there as well - just MAKE SURE you edit the jamroom/config/settings.cfg.php file BEFORE you run the “install.php” script, and update the “table prefix” setting to use a unique database table prefix:

#-----------------------------------------------------------------------
# DATABASE SETTINGS
#-----------------------------------------------------------------------
# database prefix - if you would like the tables that jamroom creates
# to start with something other than "jamroom_" you can enter it here.
# default value is "jamroom_".  This value MUST be changes prior to
# running the "install.php" script in order for it work correctly!
$config['db_prefix'] = 'jamroom_';

Note that the Jamroom license will allow you to run another copy of Jamroom only if it runs in the same domain - i.e. “jamroom1.yourdomain.com” and “jamroom2.yourdomain.com” If you want to use another, unique domain name, you need to register a copy of Jamroom for that domain.
