Not sure if this was mentioned before, but... If there are multiple forums at the same site, it can trip on different users using the same ID on both sites. I checked it out on a test forum -- created new users & got the notifications that multiple users logged in from the same place. Once installed on an active forum, a new test user there ended up with notifications that listed users that certainly never used my PC, simply because they had the same IDs as the test users on the test forum. That might explain some false positives.
