joey you should get demoted for not knowing how to use commas

Talia_ Use a comma to separate an adverb clause. Adverbial clauses begin with subordinating conjunctions, which connect the clause to the main sentence. Adverbial clauses are always dependent because of these conjunctions, and they cannot stand on their own. They may be placed at the beginning of the sentence or elsewhere
