Loading Webfonts on your server is a long, unfriendly process, and fundamentally incompatible with most online portfolios. Avoid purchasing fonts here if you are not very skilled with code. They do not mention this issue during purchase and do not offer refunds or service support. Having extensive experience with fonts did not help me install them. Overall a terrible experience.
It is now 25 July '22, and I've not gotten any reply from New. Myfonts. I'll not use them again and I'd suggest that anyone looking to buy fonts, look elsewhere.
While putting together a website mock-up, I needed to figure out what font I was looking at so that I could reproduce it elsewhere. I googled and found My Fonts' 'What the Font' feature (http://new.myfonts.com/WhatTheFont/). You upload an image of the font, and the feature helps you identify it. It got Bodoni for me but not Slash Hmk, which was a bit more complicated. So obviously it's not perfect and might not get you what you want, but it's pretty neat.
