Hi Jenna, welcome to our forum! You can communicate with anyone in this forum, either openly via forum posts or via direct messaging (the "PM" button), or by looking up people's email in their profile and contacting them in that way. Just remember that most course students drop out of the forum once they are done with their certification posting. So if a thread has gone 'cold', you most likely won't get a response. But there are always plenty of active threads happening.
