Welcome to the forums the Shaffer Family! The community in the forums are genuinely the nicest users I have seen, and it's so easy to trade!
Just, well, be warned to stay away from the
Brewster's Cafe if you don't want to face some political threads.
If you need to ask any questions about the forums, I would suggest visiting the
Bell Tree HQ
The
TBT Marketplace is for buying anything really with TBT bells, which is a form of currency here in the forums. The current rate of 1 TBT Bell is 200k IGB (In-game Bells) which is a lot right? And it's so easy to get! You simply need to post and create threads that have at least some long sentences, the more words, the more tbt you'll get!
Other than that,
The Train Station is for making friends, visiting, and so forth.
The
Re-Tail thread is for trading/selling/buying in-game ACNL items, like furniture, etc.
The
Villager Trading Plaza is for well, trading villagers! You can trade/sell/buy/giveaway any villagers! (As long as they're adoptable!)
If you need any questions, feel free to ask the Splatoon Weeb
