Animal Crossing: New Leaf

Rin, if you need help, just call me and I can help you to clean your town.
 
If you're planning on not playing this for a while, it always help to leave the Keep Town Beautiful ordinance up.
 
After seeing Chuggaaconroy's Let's Play long enough, I've been slowly more tempted to get this game sometime soon. Anything I should know as someone who's barely played any past Animal Crossing games? (I may have rented the Gamecube Animal Crossing at one point but I was just a kid at the time and didn't entirely understand everything)

I think I got the basics by watching Chuggaa's let's play though.
 
i just started playing this again after 3 months
only had one villager move out, who was rooney, so that wasn't as bad as i was expecting it to be
also i found a four leaf clover, and i'm wondering what i'm supposed to do with it?
 
It'll negate bad luck (excessive tripping) if you keep it on you when you have any.

I think it also gets you a whole bunch of HHA points if you display it.
 
If anyone's island has the cabana wallpaper, can I either go there and get it myself or buy if from you (if the latter, I am willing to pay anywhere between 40,000 and 100,000 Bells, since I can't pay in island medals), please?
 
Go to the Island past 7 and catch Palm Tree beetles
