I know this is going to sound like a newbie question even though I've been here nearly 8 years, but it's not something I've worried too much about until recently.
Where would I go if I needed to get a question about having an achievement adjusted or removed? Would I file a ticket or is there another subtopic link I need to go to in the forums?

If it's a specific issue that you're having with one of your achievements that was not awarded correctly or is showing the wrong level of completion, it's usually best to submit a ticket and they can get it fixed for you.
Thank you much. :)
