I had another talk with our partner in charge. He has asked me to stay on board until end of April, to ease the transition. Two weeks is not enough time for a newb to learn whats happening with a 56 storey building.
Heh, now I gotta break THAT news to my new employer.
Also, the partners want me to keep in touch with them, regardless of the time I'm going, 2 weeks or 10 years, they want me to keep in touch. Sealed with a handshake, and I'm back on track.
