I made a research and found a standard lib in ruby (URI) that do this parsing.

Thanks! (:

#!/usr/bin/env ruby
require 'digest/md5'

def gravatar_url(email)
  gravatar_id = Digest::MD5.hexdigest(email.downcase)
    "http://gravatar.com/avatar/#{gravatar_id}.png"
end

puts gravatar_url("[email protected]")

I would prolly do this.
