We're a pretty laid back clan. No real requirements other than to participate! We want our clan members to have fun platooning with clan mates, and to join in when we have strongholds battles.
Install Discord (discordapp.com) It's completely free. You need to have it to be able to communicate with clan mates and is a must for detachments. If you want to do more than just play, INSTALL DISCORD!
Discord will be used to announce things like tournaments that you can enter and it can be used to post links and screen shots of your great battles.
Once you have Discord installed, ask in chat and someone should be able to send you an invitation to the MARV room so you can chat to clan members.
Most of all, just have a good time!
