Active support

You want to become an active supporter of the C3S? That’s awesome! There’s a lot of things to do and we can use any help. No matter what field you’re in and what you wanna do (organise parties and concerts, IT/web-development, PR or just help with some office work), there’s probably a place for you.
Just write an email to Veit (, internal organisation), telling him what you would like to do, which of your skills you would like to bring into the project and how much time approximately you’re offering to spend on it.
