Okay, so first of all, you should sign up and get an account. Pokemon Questions are not allowed in this forum.
But, I'm already posting here to tell you that, so I'll answer it as well. Go to Vermilion city, and go to the ferry dock there, where the SS Anne was originally. From there, you should be able to ride a ferry back to the Seveii islands, where you can follow the Seveii Islands Walkthrough on the main site, to make sure you don't miss anything important.
