Also Urgent, British people what the heck is a "copper bottomed pledge"?

It’s hard to be certain, because there’s context missing here. A pledge is a promise (of course), and you don’t indicate anything about having given a promise or said anything about anyone else’s, so I’m sort of in the dark here about the full context. But… a “copper bottomed pledge” should be taken as one that is solid and serious.

In the days of wooden ships and the British navy, the capital ships that were built to last for a long time and see duty in the tropics as well as northern latitudes were sheathed with copper on the bottom to prevent shipworms (teredos, I think) from penetrating the wooden hull and weakening it.

You’d only go to the expense of sheathing a ship with a copper bottom if you had a lot riding on it and meant for it to last. So a “copper bottomed pledge” is one that is serious and meant to last.

It has weight. Is strong and reliable. Referring to the pledge being Genuine; trustworthy.

^as above answer states it originates from copper plated ship hulls.

Context. The email. Should I assume he means that me saying “That’s all I got” is selling myself short, because I gave good, solid, information?
—After doing a little closer look at the links. I like alot of the material that is in there. It brings back good memories of college AND refreshes thinking strategies. One big thing I don’t like about the first link (FL) is the presentation of their material. It might have little to do with the books merit, but I hate having to click around 100 links to get new information. Second Link (SL) gives me a PDF and I can scroll easy to retrieve info.

Another thing is the first chapter, FL immediately delves into credibility without talking about argument. One of the things I loved about logic and critical thinking was from day 1 you learn how to rethink your arguments and it seems like SL is definitely laid out a little better that way. And along those lines SL does a slightly better job presenting the vocabulary you’d study from the book. After Unit 1 FL doesn’t let you peek. (I understand protecting their product, but come on…give us a little bit more to get a feel for what we’d be teaching)

Moving forward: from SL I see things I like such as: fallacy, dilemma, ethics, and a few different sections in different chapters that are on reasoning and argument.

No matter what choice we make I am sure that there’s a similar payoff for both. The material probably isn’t that much different either (FL does have a section about Prince Harry groping some girls breast though!). When I first went to college I was a very unsure person, and unordered in my thinking, after taking logic and critical thinking early on I felt more ready to tackle my University courses. When I’m actively applying the principles I learned in those classes I’m a happier person than when I get lazy with them.
That’s all I got—

why isn’t it whispering?

I come from a place not far from Hull but I have never heard of this saying before. I found it used in context here and it seems to imply a pledge that is solid and reliable. I expect it comes from the idea of copper-bottomed pots and pans, that are also solid and considered to be good quality. So I think your boss is complimenting you.

@jlelandg do you have a minimum font size set in your browser? I never see whispers because I have a minimum font size set.

it means it’s water tight, naval ships in the 18th century were wooden with copper plated hulls to reduce barnacles, rot and increase hydro dynamics, but in this sense it means a sure thing.

@mammal ooh thanks, I didn’t realise there was a nautical connection.

@jlelandg I think it’s because you’ve put line breaks in (enter/return) :-)
