So I've read all the answers in the first posts and I think my questions are just so newb no one else has asked them. XD
1) When people list their residents, and say dreamies, what do they mean? Are those the one they wish would move in?
2) What is this business about selling/trading residents? How does that work?
3) Trading/selling items with other players... that is done by inviting them over/going to their town and and dropping things on the ground?
Sorry if these are so basic it's annoying. I learned a lot just reading the already asked questions, so thanks for making this concise and collected thread. <3
You got the basics down at least ^__^ I am also fairly new, since I've only been playing for a few months compared to a year from other people.
I'll try to answer your questions, I hope in an understandable way XD
1) Dreamies is a concept for people's favorite villagers who they want to have (so move-in) in their towns and want to keep there. Since the games allows for only 10 villagers, dreamie lists usually only lists 10 villagers, although some people have more or less so they can rotate and enjoy new faces every once in a while.
2) Selling/Trading/Giveaway villagers revolves around the move-outs of villager. When you have 9-10 villagers in your town, occasionally someone wants to leave. People put them up for sale/trade/giveaway to find a new home for them. If a villager is in 'boxes', it means he/she is packed up and will be leaving his current town the next day. During his 'boxes' day, someone from another town can come over, talk to the villager and convince him/her to move to the other town (you need to have less than 10 villagers to be able to get a villager to move into your town). The villager's data will be transported to the other town where he will move in the next day (sometimes 2-3 days I believe), leaving his old town.
Some people sell their villager for Bells, or trade them for a villager they want themselves. Other people give villagers away.
Some seller require 'dreamie proof', which is basically a signature picture or text in which is stated that this villager is a dreamie of yours and you really really reaaaaally want it. Mostly this is because they want to give their villager to a good home where he/she is really wanted and will be loved.
3) Trading/selling items is mostly done as you describe it. You visit the buyer/seller's town or he/she comes to you, and the exchange happens by dropping the items to the ground. There are several guides as how to keep an eye out for scammers. Overall, on this forum I think almost all people are honest and sincere and no scammers, plus, you can check their Wi-Fi Rating on their profile page to see whether other people have given them positive or negative Wi-Fi ratings. Negative rating can also be caused by bad Wi-Fi connections, but also by having a negative attitude or stealing etc. It's a reasonably good indicator whether you want to trade with this person or not.
I hope this helped! If you have any more questions (or mine are not complete), I'm sure there's loads of other nice persons here to help you out! ^_^
