For example, one of the forum users might be a recent mother that slowly goes through pregnancy...And then a baby appears in one of her arms.
Another possibility is to have someone post in different rooms that are shown in the background, depending on what angle you decide to use. This has plenty of possibilities. For example, one of the forum-goers parents are divorced. Or is hanging with the wrong crowd. Or retreats to his/her room while a fight is happening right outside the door.
Or you can go lighter and have amusing events. Like a rowdy family, or an eccentric roommate. Or tons of textbooks and papers all over the dorm room. All you need to do is to write up the basic "arc" for five or main regular forumgoers. The sky's the limit.
