There may be a couple of reasons nobody has responded to your post. First, there are other Penn Foster Students that read the forums here at eLearners, but perhaps they are in a different program, so they aren't able to answer the questions you are asking. Also, everybody who reads these forums does so on their free time. I think I can safely say that everybody who attends PFC has a job, family, kids, and plenty of other things to do, so replying to a forum post probably isn't at the top of the list of their things to do.
At eLearners, people can read posts without signing in, so that may be why it only looks like there are a couple of people checking out the boards. You can only see the ones that are actually signed in at any given time. In actuality, there are many more people on the boards than you can see.
By the way, Penn Foster College does have its own blog, but not a forum, which is probably what you meant. You can check out Penn Foster College's official blog here. Like you, I do wish the PFC courses were more interactive and allowed for communication between students.
There is also a Penn Foster forum at eLearners, as you know, as well as two blogs: one about Penn Foster College and the other about Penn Foster Career School. If you have any specific questions about the Paralegal program, have you tried asking the school itself? I recommend calling, rather than email. You will get a much faster response that way.
As for the school being 'real", I'm not sure what you mean. It is accredited by the DETC, which is an accrediting agency recognized by the U.S. Department of Education. That's about as "real" as it gets.
Good luck with your studies!
