Hi, and welcome to the Magimon community! You seem to be new here. Don't worry.
We have a topic to add friend IDs here. Just post it here, with your Faction, Element, and username! It's pretty simple.
Unfortunately, there are no guilds/clans at the time, just two factions. Hopefully, they will be added soon!
Magimon trading/gifting is not implemented, but also this may hopefully come along soon.
Other than that, welcome to the game!
