Learn Italian: Anche tu fai parte di questa comunità. - You too are part of this community.

In Italian, the standard expression for "to be part of" is far parte di (literally, "to make part of"). Because it is a set phrase, you must conjugate the verb fare rather than essere.

Why is anche placed right before tu?

In English, we usually put "too" at the end of the sentence ("You are part of this community too"). In Italian, anche (also/too) is placed immediately before the word it emphasizes. Here, putting it right before tu clearly focuses the meaning on "You too" or "Even you".

Why does comunità have an accent mark on the last letter?

The accent shows that your voice should stress the final syllable. As a helpful trick, many English words ending in "-ty" (community, city, university) translate to feminine Italian words ending in -tà (comunità, città, università). These words are invariable, meaning their ending stays exactly the same in the plural!

Why does the sentence use questa instead of questo?

Questa (this) is a demonstrative adjective that must match the gender of the noun it points to. Since comunità is a feminine noun, you need the feminine singular questa.
