Mission accomplished, the text went well, I'm in!
from a 202 phone number, Tuesday, December 16, 10:48 AM

I'm hoping that 202 has a crush on some guy so for her first "move" she sent him a text message, and it "went well"-- maybe he responded to her in some encouraging way?-- so when she says "I'm in!" she means that she and her crush are going to go out on a date.

Currently accepting alternate explanations, if you've got any.
