Is it safe to assume that two geeklog sites can be installed on one server as long as there are separate directories and databases??

Yes, that's possible. You can even run them from the same database, provided that you use different prefixes for the table names (that's what $_DB_table_prefix in config.php is for). bye, Dirk

So if I got this straight I can add say gl2_ and gl3_ etc to config.php then just add the public_html to the other sites and we're good? Or do I create a different config.php for each site?

The easiest way would be to have two complete (and separate) copies of the Geeklog code. Although it may be possible to share some of the directories if you fiddle with the path settings a bit. But you need at least separate config.php and lib-common.php files ... bye, Dirk
