Add multi address into maillist in one time

[hairihan]

Hi HashNuke,

How can I adding several email addresses into one maillist in one time?
I tried to using following method, but it's only support to add one address.
It will cause timeout err when there are a plenty amount of address.

# Adds a mailing list member with a given address
    # NOTE Use create instead of add?
    def add(member_address, options={})
      params = {:address => member_address}
      Mailgun.submit :post, list_member_url, params.merge(options)
    end
