It was actually very easy! If there's one thing TA is most popular for, it's the near-flawless organization skills. Whatever letter you're on, you just click it and it'll direct you to a list where it scans your game library and automatically display every achievement you haven't earned that starts with that letter. It doesn't show for games you haven't started yet obviously--but it's still a VERY handy tool.

Wow, that's awesome.

I made an account last time you posted about the site, but then I totally just forgot about it and havne't logged in since. I need to explore it some.

You just gotta take it over the top

Since it doesn't appear that there is an achievement that starts with a "!"
How about this one?
¡Fiesta!
Happy Birthday!
Congratulations! Happy Birthday!
or maybe this one? It is listed in the "Highest Scoring Achievements" pane on the right side of the screen
Perfection!

I'd have given up at the "Look up achievements that start with the correct letter" step.

Considering how many games and achievements I had in my backlog, I felt this would be a great and fun way to clear some of them out and revisit old gems! From March 10th to 23rd, I searched and binged like crazy to get as much of a variety as I could, instead of just getting the easiest cheevos. While there are some I missed, and at least one game I wish I had pushed myself on, I still say I'm very proud with the results!

In order, I got the:

• Heavy Metal achievement in Alan Wake
  
• A Friend In Need achievement in Alan Wake
  
• Petty Vandalism achievement in Yooka-Laylee
