tracker module with a uid - omits posts

i suggest that the query which produces the tracker page of a specific user be changed like this:

SELECT n.nid, n.title, n.type, n.changed, n.uid, u.name, 
MAX(GREATEST(n.changed, c.timestamp)) AS last_activity 
FROM node n LEFT JOIN comments c ON n.nid = c.nid LEFT 
JOIN users u ON n.uid = u.uid WHERE <b>n.uid = '". 
check_query($id) ."'</b> AND n.status = 1 GROUP BY n.nid, 
n.title, n.type, n.changed, n.uid, u.name ORDER BY 
last_activity DESC

should be

SELECT n.nid, n.title, n.type, n.changed, n.uid, u.name, 
MAX(GREATEST(n.changed, c.timestamp)) AS last_activity 
FROM node n LEFT JOIN comments c ON n.nid = c.nid LEFT 
JOIN users u ON n.uid = u.uid WHERE <b>(c.uid = '". 
check_query($id) ."' OR n.uid = '". check_query($id) 
."')</b> AND n.status = 1 GROUP BY n.nid, n.title, n.type, 
n.changed, n.uid, u.name ORDER BY last_activity DESC

this way, we can track everything the user has produced. including the comments he wrote under other peoples nodes...
