At my forum we play the a few forumgames like:
Ken je het en keek je het? (Do you know it, and did you watch it as a kid)
In this game a person post an old TV-show or cartoon he or she saw as a kid. The next person replies to it if he watched the show or not and post a new TV-show/cartoon.
A person starts with a word wich begins with the letter where the last word ended.
Like Snake - Edit - Transparent - Telegram - Master...
Jij bent 'm (You're it)
A person post something like 'If you have glasses, you're it'. A person who has glasses may reply to the post with something else like 'if you hate milk, you're it' ...
These games (and a lot more) are people playing on my forum.
What kind of forumgames are you playing on you'r forum?
