The best way to do this is to contact other members by doing a search on "Find a Language Partner". Just do a search on people who know English and want to learn Spanish or who are willing to help others with their English. However I recommend that you get someone who also knows Spanish so that when you have doubts on how to say something, you can easily switch to Spanish and the other person can help you out. You just need to send an invitation to a person to become friends with them, then you can exchange contact information (so you can chat through e-mail, Skype, Messenger, Google Talk or any other instant messaging system) and keep in contact with that person.
Remember that the best way to learn a language is to practice every day. Good luck!
