New gmae i ahve just though up. Basically, as the thread goes on, each poster thinks of a rule to apply to the first the next post.
For example, if some posted first and said:
The next thread must be written backwards
Then the next thread must be written backwards, including the next rule to be applied. Dont be afraid to reuse rules if you cant think of one, but please try not to apply the same rule over and over again, and explain the rule if you think it may cause trouble.
I start:
The next post must be written,
struck through.
Enjoy
