One problem with the site is the "Wiki" button.

While people that have been around know where it is, someone new to the site will easily glance over it.
The button itself lacks any information other than it is a Wiki. Changing it to a flashing graphic (or something eye-catching) and making it a litle more descriptive would help.
There is a LOT of information on the first page for a new users to take in (including a lot of links)..anything to draw more attention to items you think people should know first would be a good start.

I'm not sure if it can be done with the forums, but putting a direct link that "looks" like you are going to a forum might also help. The more ways to get to the Wiki, the less chance people will have to look over it.

Sometimes people search so hard for something, they miss what's right in front of them....My keys come to mind. :P
But it doesn't mean they aren't looking or putting forth the effort. That being said, there are some people who just refuse, and there's nothing that can be done for them.

It would be funny if it was possible to add another button into the Message editor that would auto-populate a response with "n00b" information and links.
