With all due respect to those who have used and maintained this website through its history - and I do recognize that this is one of the focal sites when it comes to SimCity 4, but as a new user to the site myself, I understand the confusion that other new users are finding with this site.
In short, I find the whole organization method of "everything goes in a forum post" very difficult to work with. I don't know if it's the whole mindset/paradigm I have, but I've always treated forums as the "discussion goes here" part of the website, but other general, static information, like "what is gmax? where can I get it? how can I learn to use it? what is STEX? what is NDEX?" should go into a simpler FAQ/Link/Information page (or series of pages) outside the scope of the forums.
Again, I'm only speaking from personal experience, but when i first found this website, I was a bit confused by the fact that, in a sense, it has no "home page" - it simply lists an overwhelming collection of forums, each on a different topic - and as a new user, I don't know (or didn't know) what all these topics even meant (for example, BAT, NDEX, STEX, etc.).
Digging through days, months, and years of posts to find an article with the basic information you are looking for tends to be quite tedious, and I'm sure after paging down a few times, it's easier for a newbie to simply add yet another post, asking the most basic questions - which is fine if you ask me for a format such as this - but I see that some number of people get quite frustrated with it.
Anyway, i think you get my point. Just adding my $0.02 to the discussion by saying that it's not the lack of information at the site (well, at least while the site is under re-construction), it's the organization and difficulty in finding the good, relavent information. I think this site would go a long way to correcting this if the "home page" were replaced with a FAQ page, or list of links, with links into the appropriate locations in the forums (sort of like The Tips and Tricks Site at simcity.ea.com), for example, instead of the home page simply redirecting straight into the forums.
