I repair computers professionally, but this this is not about your being unsavvy on computers. It's about the silliness of trying to make every site into a social networking venue. There's nothing wrong with you.
You and I just see the silliness of it. I expect "like" and "dislike" buttons to appear in the software soon, and ratings for each thread and each post: "Was this reply useful? Rate 1-10."
You can't remove the "Remove your thanks" button, sorry. You can threaten someone with it. :D
