I'm curious about something. Occasionally I see a post where someone points out that this poster or that poster is actually someone who has returned to the DIS boards under a new name. How can anyone tell that, unless the "new" poster reveals it in a PM to someone else or comes right out and admits it openly (which I wouldn't imagine would usually happen). Is it just a suspicion by the person pointing this out, or is there another way to tell? I've wondered this for a while, so decided to finally ask.
