Why/How did this "に" get translated into "and"?

[Ongakuka]

Nilecatさん, I truly appreciate the amount of detail and thorough explanation you give for us 外人。 It means a great deal, thank you so much!

I'd like to note that I would have translated the に as 'as,' since 'with' often has the meaning of 'as well as,' which is I believe a close approximation of the particles meaning (when it has the function of 'listing.')

That "に" feels like an "on top of ..." to me, but it's pretty much the same as other translations mentioned earlier.

Just my 2 cents.

sorry I just read what I put there... I'm sure I meant I would have translated it as 'with' (like the original) and then I go on to explain that reason.

Sorry if that was confusing :s

can't に in listing purposes be like aa "and" but with a "moreover, and beyond that" or even a "with" nuance.

に is "AND" but with a "MOREOVER" "ON TOP OF" or "WITH" sense to it. Or so I believe in this instance.
It's stressing something that makes the first listing even better. BLAH NI BLAH 2 BLAH 2 is making BLAH better or the subject/overall thing better.

I have to say, not to be off topic, but Welcome Retsubty! It kind of blows my mind that you're just now posting on the forums for the first time, since we've been chatting in the chat for what literally seems to be years now (I guess it's only been several months).

ようこそ！ (pardon the off-topic comment on this thread, I just feel compelled to welcome our friend's first post!)

Yeah lol I just felt like checking it out. I didn't realize that it would post my post later on so I accidently rewrote it and posted again.
