Tangentially, if you communicate to Alex regularly, can you please point out that the "Rules" page linked at the top of the site still doesn't link to the actual enforced rule set in your (and my) sig? I've repeatedly contacted Alex about it myself, and he hasn't done anything about it. I have seen instances (although thankfully not as much recently) where relatively new posters have gotten banned for offenses that they probably didn't know were against the forum rules, simply because the rules they had consulted weren't the same set of rules that the moderators actually use.
Preaching to the choir.
But let's not turn this into a "Alex needs to......" thread.
This thread isn't about the new guys, it's about folks who have been here for years who really have no excuse to not know how this place works.
That said, if a new user comes on here just to be a dick, I have no problem setting them straight or just pulling thier card.
If you read the "old rules" that are in the "Rules" tab the basics are pretty much covered: don't be a dick, one account, etc. Most of the rules in the current batch are more specific, but it's not like new users are getting banned for posting "pre-NGDs" or necro-bumping and other minor etiquette things.
The main source of new user bans are for issues related to the Marketplace which has it's own set of posted rules. There's no excuse for breaking those.
