So what are these strange usernames, anyway? Within the past hour or so I have seen u5i6u2q8s, ui519q4h, ui530q4c, ui845q6c, u5i5m8q9s show up at the bottom of the page as logged in users. Yesterday, I saw at least 3 strange letter/number names show up at the bottom of the page as new members. Very strange.
Sounds like a bunch of part numbers trying to join the forum.
