Though the Hivemind has no rules, per se, there are a few (two) guidelines we try to keep in mind. I thought I'd mention them for our new friends.
1) We generally end Hivethreads at around 400 posts. This is for database reasons, and keeping some of the clutter on these boards to a minimum.

Also, we try to completly ignore the ones we have "finished" even carrying over conversation to the new Hive. Having multiple Hives on the front page always irks someone or other.
2) Generally, the Hive is a sig free zone. This is not a hard rule, but really more of a courtesy, especially if your sig is large or contains pics.
That's it. These were decided on a long time agao to keep our detractors a little less rabid. Now, back to your previously scheduled Hivemind.

Like I said, these are not rules, but they do prevent some issues with other members.
