Funny how things have changed. In 2015 when I first found DD, there was a lot of helpful info. Now not so much, or I miss it as I rarely come here any more. I understand the reasons for the change but sometimes I think it’s just better to ignore a post versus being snarky.
To the poster with the Amex question, pick a year, start there, and read through thousands of posts. That’s what I did. You’ll still have to separate the chaff from the wheat, but will learn a lot and may be able to extrapolate some of the info.
