Let me make one thing perfectly clear
When I say "I'm not interested in running Minicon 42" this does not mean that I am interested in running Minicon 43. Or to make it even clearer: I'm not interested in chairing Minicon 43. I might be convinced to consider chairing/co-chairing Minicon 44 but it would probably take something along the lines of a group of people coming up to me and saying "Hello, we are a fully formed Minicon 44 ConCom and we're looking for a chair. Are you interested?"
