Some MU mutants just want to do their own thing, but as Bono sang "sometimes you can't make it on your own". Which mutants should stop faffing around, being all assimilationist, and join the X-Men already. For the purpose of this poll, joining the X-Men be defined as being an official team-member of one of the teams from Adjectiveless, Uncanny, Astonishing, or even New X-Men: Academy X. So X-Corps, X-Factor, X-Force, Excalibur, etc. don't count.
