Well, *I* don't understand the poll (LOL)
"What percentage of UG members have read the rules? Part 2: and understand the rules ?"
How would *I* know ?
First of all, some of the board software needs to change. Trust me. I do some of this for a living.
When somebody signs up, and even when existing members "log on", have a "pop up" box come up and say something like "You MUST read the rules before posting (again)" There should be a link within this box to the rules.
They click on the link and get to the rules. At the end of the rules, just like an on-line licensing agreement there is a check box. "I have read the rules and agree to abide by them."
Now, as for the rules themselves. There are WAY too many of them and they are WAY too wordy. People don't like to read what they don't WANT to read. You have to keep them short and simple, otherwise they will go to the end and simply check the "agreement" checkbox.
You repeat a certain rule (I forget which) MANY times. You also have some rules that are written tongue-in-cheek, or at least appear to be (like "Don't pester the APM"). People see that and assume you are joking and they need not take the rules seriously.
If there are 2 or 3 VERY important rules, have those rules, written very briefly, pop up every time someone signs in whether they've agreed to having read the rules or not. It's very easy to close that little pop up box.
Just my $.02 (2 cents (LOL))
