what is actually our mission gathered in this bitcointalk forum, what just looking for money what the fraternity between countries or between cities .. please his explanation 
If you following the terminology, then a forum is a place to gather and share same interest between the member, so your mission is to be just like a normal human do, interact, but because this forum is about cryptocurrency (but the biggest highlight is nitcoin) then you should talk about it. Well, you can hang around too in other category and talk about others. Just like real life right?
But because things are getting worse in here, i guess your mission can be added as :
1. Do not join the spam army and bots
2. Help fighting the spam army and bots.
That is all i think.
