Hi Zero,
If you're just looking for the 5 most recent posts you can do a simple query such as this...
PHP Code:
SELECT
b.title,
a.threadid,
a.username,
a.userid,
a.dateline
FROM
". TABLE_PREFIX ."post a,
". TABLE_PREFIX ."thread b
WHERE
a.threadid = b.threadid
AND b.forumid NOT IN ()
ORDER BY
a.dateline DESC
LIMIT
0, 5
For "AND b.forumid NOT IN ()" just include forum ids (such as staff / warnings / private / etc) you don't want shown.
