Of course. Exactly the same principle applies.

Replace this

// Change the prefix if you want to have multiple forums in a single database.

$bb_table_prefix  = 'bb_'; // Only letters, numbers and underscores please!

With

// Change the prefix if you want to have multiple forums in a single database.

$bb_table_prefix = ereg_replace('^(www.)', '', $_SERVER['HTTP_HOST']);

$bb_table_prefix = ereg_replace('.', '', $table_prefix);

$bb_table_prefix = $table_prefix . '_';

That is all.
