When you agreed in writing in August to speak at an event in November, and I've now contacted you 3x this past week to confirm and finalize details and you have not responded to anything, I'm wondering: did you fall off a roof? or is this the new etiquette of "I'll actually only do it if I feel like at that moment"??
Now I have to take time off to go this person's workplace and hunt them down. Extremely unprofessional on their part.
errk - am editing my post because after a personal visit, all was resolved and event is going forward. Still wish I had been kept apprised of the situation, but now All is Well.
