lol, i know what youre going through, but i havent sent a text message i regretted too much. one time though, i emailed a confidential letter announcing the termination of some of our top sales people and instead of sending it to 'blackberry support' (which is about 4 dudes in IT), i sent it to the 'blackberry group' (approx 1200 people). i got a response from people asking wtf this message was about and a VP who managed the terminated people emailed me pissed off. Very fucking embarassing - i thought i was toast for sure.
