1.In the comment form, I don't want the website field. Name and email are enough?
I already disabled it from your backend.
2.Who will receive the comments by email? I have received your comment as administrator, but I'm not sure if they are sent to the members of Blog Administrator
When the user comment on your blog post, the blog author will get notified.
When the second or third user comment on the same blog post, only blog author will get notified.
Unless who comment on that blog post it tick on that subscribe checkbox (screenshot :

However, you can adjust those comment notification from backend setting ->

By the way, I would always encourage our customer to start a new thread on our forums with the new question or issue, so they will get faster response from our multiple moderator and easier to manage your current issue.
Thanks for understand.
