I used Doctor Agenda as my username on a superhero rpg board, because I thought it sounded like a supervillain. I changed it to Mister Agenda for other boards since I'm not a doctor and didn't want the hassle of people thinking I might be one. To an extent, the 'Agenda' part is useful in reminding me that people can have an agenda for what they post that isn't obvious. I tend to be slow to pick up on such things.
I'm not anti-Christian. I'm anti-stupid.
