Learn Dutch: De vegetariërs koken niet meer voor elkaar. - The vegetarians do not cook for each other anymore.

We use niet meer because we are negating the action (the verb koken). It means they are no longer doing the cooking. You would use geen ... meer if you were negating an unspecified noun, for example if they cooked no more meat (geen vlees meer).

Why is niet meer placed before voor elkaar?

In Dutch main clauses, the negation niet (and the phrase niet meer) generally comes after the main verb but before prepositional phrases (phrases starting with words like voor, in, op). So it goes between koken and voor elkaar.

What are the two dots on the 'e' in vegetariërs for?

That symbol is called a trema. It tells you that a new syllable starts at that letter. Without it, the ie would be read as a single sound (like the ee in the English word see). The trema ensures you pronounce the i and the e separately: ve-ge-ta-ri-ers.

Can elkaar be used for more than two people?

Yes! The word elkaar translates to both each other and one another. It works exactly the same whether there are two vegetarians or a whole group of them cooking for each other.
