I thought as much because you're usually a really good, helpful poster, but I think the sort of ribbing derDoc did was more appropriate than your sarcasm, especially after it seemingly (imo) wasn't being taken as such. As far as the OP, a few people were able to respond before you brought it up, and I'd be much more apt to just say I don't understand or even move to a different thread if I simply don't understand a post's question, but that's just me.
