Suggestions for the rules:
Remove rules like "avatar size requirements" and the forums in which polls are allowed, as these are enforced by the forum . Also, sneak bumping is impossible now as IIRC the new forum doesn't allow normal users to delete their own posts.
Split them into sections. Newbies don't need to worry about signature rules if they just want to ask a question.
Just spell out each rule, rather than explaining the reason for it.
Make them easier to follow. For #7, just ask the user to click Utilities -> Check for Updates before posting.
Combine similar rules. #12 and #24 could be combined to say "Family friendly forum. Don't swear or post NSFW art."
