CTRL+F. That's why.
Because seriously, the post your ID thread is just plain stupid.
I decided to compile the IDs from that thread to make something useful out of it, because searching is clunky and doesn't always work, and because the OP hasn't been on for about two years. Additionally half of the links and IDs are broken, I spent some time filtering those out as well. I don't mind spending a minute a day adding people to the list, so feel free to send me a message or post if you'd like to be added. I would prefer for you to post your community profile link rather than your IDs as links are generally far more convenient.
