ACL's advice is very good. This is a public forum. I addition I would remind everyone who is a Delta employee about Delta's policy on posting on the internet if it regards the company. I have heard through the grapevine that some posts have attracted attention. I hope there is no follow up because I have read many posts that are clearly in violation. If you want to slam Delta online I would do it on the Dalpa forum that is not public. Delta has used forum posts before to go after pilots. Be careful and think about what you say.
