1) Reply here in this thread saying you want to do the achievement
(For security reasons I am ignoring friend requests without reason)
2) Send me a friend request; I will accept and contact you via PM.
3) I will host a game for you and let you win.
4) After we are done, we can unfriend us. No hard feelings

Nothing—I just want to help.

I am happy to help some fellow gamers.

Why did you unfriend me?
Steam has an upper limit for friends. Additionally, I like to clean up my friend list from time to time — it's nothing personal.
If you prefer to stay on my friend list for any reason, just let me know.

I am waiting and you did not send me a friend request
Please send me a friend request instead — for organizational reasons.
As you can imagine, helping many people leads to some "organizational confusion."

I sent you a friend request and you did not accept
Probably my fault. Just write me again on my Steam profile or in this guide — I might have missed you, sorry.
For context: I receive multiple friend requests and I don’t accept them without a reason, for account security and scam protection.
This causes a bit of a "flood" that I have to work through.

I really want to help you somehow
No need to do that — I just helped you get one achievement, and it took me ~5 minutes of effort.
If you want to help me, take inspiration from my actions and help other fellow gamers on Steam.
We’re all part of the same platform, and gamers should help each other. ;)

There are also some of the people I already helped.
