vB3 One member base, multiple forums

[Andreas]

This is not that easy to do.
You would have to edit all PHP-Files to have a special prefix for the tables user, userfield and usertextfield.
You would then have to install all forums into the same database using different prefixes - except those 3 tables which must have the same prefix (or none at all).

Furthermore, you will run into problems like usergroups, post counter, last activity,etc.

And you will need multiple licenses.
