Wanting to join college Anime club but not sure if i'm ok with everything they do....?

I'm sure the members of the club would understand if you don't want to do the Japanese lessons or cosplay--especially if you're already studying two languages! There are probably already members who don;t join in everything the club does. It would be a pity if you missed out on the whole anime club just because you didn't want to take part in a few of their activities.
