Zombie, my "hack" is not WOL, which is included in UBB 6.2, it's an addition to 6.2.0/6.3.0's Recent Visitors (which is like WOL).
d-talk, why do you like q's WOL better? If it's because of the WOL/Recent Visitors pages (?ubb=pntf), try to use my "WOL List" hack. If it's because it doesn't tell you when a user creates a new topic/etc, use my "Extended Recent Visitors" hack. Anything else?
