For my data analysis, I would like to present this bluntly titled thread: Rules of FGD (Fighting Game Discussion): Read Me First Or Be Banned IRL This thread basically presents its own Ten Commandments for how one should regulate his or her activity within the forum. You'll see the modal "should" appearing frequently in the moderator's posts, which of course reflects the normative purpose of such a thread. One important thing to notice: this is a locked thread--which means no one in the community may contribute, except for those with the password authority to do so. I feel that such a highly prescriptive, monological (single-voiced) thread represents anti-discussion; it establishes a system of rules, while negating the democratic function of group participation through the thread's lock function. There is also a heavily penal dimension to the moderator's comments, what with all the punitive signifiers: the verbs "infracted" and "banned" being the most conspicuous.
Also, check out rule number 4. I think such an obliging attitude toward machismo clearly indicates the gendered nature of this forum.
