Although it does track topic views and the forum_id of each topic, so you could get forum views with:
Code: Select all
SELECT SUM(topic_views) FROM phpbb_topics WHERE forum_id = X
Depending on how up-to-date you wanted that statistic, you would have to run a script to query all the forums periodically. No idea what kind of load that would be. But the Posts statistic on viewforum seems not to be too intensive.
