I see you have this community as a discussion platform with over 730 pages of questions. I see your actively engaged in the responses as well. However, do you use the Buddypress Facebook functionality in your website? If not, what is your reason for this? I thought about allowing anyone to be able to sign up to my site without paying first but realised I may get random people like myself 🙂 just sending messages. Do you do this to drive engagement and therefore promote the courses in your website? Would you recommend doing this over the Buddypress Facebook style of engagement with paying students?
