Wow. It's good to be back. But anyway, let's talk more about how to establish a smash club in our schools.
For most of the public schools, I guess its easier to make up a smash club than having one in private schools. Usually, you need to find at least 10+ interested students of the school that are already intrested in joining/helping the club. After that, (this is for High schools) you need an adviser. Now, the adviser could be any of the teachers. He/she doesn't necessarily need to be one of your current teachers. And then, you need to fill up a certain forms (a club registration form for my school) for the activities office to approve. In order to get your club to be approved, it needs to have the asst. principle's, principles, and the activities adviser's signature on it. Or else, they will not let you to start up a club. (you might also need to type up a constitution too!)
This is the most basic way of how to start a new club in most of the high schools. In college or Universities, the procedure might be different but I guess its even easier to form a club because we are older.
Finally, the easiest way to find out how to start a new club is of course: ask! Go to whatever offices you have at your school and just ASK! I think they'll be more than happy to answer questions about a smash club.
Hope that helped!
