The above link shows that someone edited my question almost 2 years after its initial posting just to remove "Thanks in advance!" While I realize (now) that putting thanks into the question is not in line with the usual etiquette of this group, it really seems unnecessary to go in and edit it out, especially after so much time has passed. To me it just seems like someone is just editing for the sake of editing to get a few reputation points. Does that edit really improve the site?
