Can anarchy still have Representatives

Okay so English isn't my first language and I'm 99% sure I'm gonna word it wrong here so feel free to ask if something isn't clear. I just recently got into anarchism and I feel like it's the best possible way to run a "society" but something isn't clear. How are large group of people gonna comunicate with each other could there be a representative who speaks for the people but does not have any power over them?
