Welcome to Friendcodes.com. Using a thread to find an opponent is a bad method, so I suggest using the Gaming Hubs to exchange Friendcodes with others:
How to Create a WiFi Hub
As you know or may not know, in order to play someone online in Animal Crossing, you BOTH need to exchange each other's Friendcodes, so talking with someone in instant chat (where your opponent’s friendcode is displayed) you can both communicate efficiently towards each other. You can also be leave short messages when chatting instead of posting a lot in this thread.
Good luck with Nookington’s be sure to buy a lot from Tom Nook. It's not that hard and generous people give MASSIVE amounts of money to you (100,000 bells for instance). Watch out for seeders though, they may trick you. Seeders are people who use a "Hacking Device" (Which isn't prohibited on this site) to hack your game for "Entertainment" which is very stupid. They add an object in front of your town's gate and house so you can't get out causing you to start your game all over. Some Hackers cause severe damage that can't be repaired, others don't.
Welcome to the site and be sure to read the rules and stay active too, I hope you have fun playing others in Animal Crossing. ;]
