Hi All, I have been pleasantly surprised at how responsive and gracious many people, often very busy ones (academia, business people, etc), have been re my requests for information, general help , especially given my not being in a high position at this point in my life. Still, while I want to show my gratitude to them with a reply email saying thank you, I worry that if I am to respond this way, I end up only taking their time and clogging up their mailbox, wasting their time in the end. I often just wish them thanks in advance. Any other way I can thank in a way that does not waste their time? Thanks.
