I was running few e107 based pages around 13 years ago (for local scouting organization or gaming ones) and i have only good memories about using this solution. Currently I am thinking about something new and i got 2 questions:
1) Is it an option to create 9gag like webpage (based on users posts) page on e107? (not nessesery based on images but more on text and image as an option)
2) Is there an option for users to register, login, comment using facebook?
