That's right -- after the last extension, the team decided to further lengthen the period allowed for free server transfers. February 28th was originally slated to be the final day, but with the weekend so close, they've pushed it ahead another week, ending either on Sunday or Monday. (The official announcement says "Sunday, March 8th." This is doubtlessly a typo, as the calendar forbids such an interaction from taking place.)
An extended transfer period means that everyone you play should be well-positioned for the double experience weekend, as well as the upcoming changes to the game. So get your smackdown on in City of Heroes wherever you want, and ramp up for the big changes just over the horizon.
