A few suggestions for people to consider.
*cracks knuckles*
Firstly, what about a background to appear behind all these boxes? Being just white is not particularly evil in any way

The current theme is a very basic one. I intend on making more dark and detailed ones with more graphics. Users could then select from multiple themes.
My initial thought was fire/ flames as this could be in character and yet not too black for anyone. They could have the colour taken right down to be quite subtle, or even black and white.
Ya, we could edit the default skin to include these. Or make a totally new theme, what do you think?
Another thing might be changing the description of the 'Rules development' area to be something more like this:
Got a new Chaos Dwarf unit or character that you want feedback on? Perhaps a new scenario, armylist or ideas for a campaign. Then post and test them here!
Not a bad idea. You have Admin powers! Make it so. 
It invites dicussion of wider things that just what should or should not be in a new book. It also wouldn't need updating then once the book comes out.
Agreed.
Also to get us on Warvault with a 'vote for us' link in the 'Chaos Dwarfs Online' section (under website news, or staff for those with that option).
By all means. What is needed for this? If any graphics are needed just tell me the size I have to make and I will do it. What's the link to this?
My final suggestion (of the top of my head), is a long term project that would take a while to do.
Check out the Wiki. My hope is that becomes one of our goals, to fill it up with our Chaos Dwarf Knowledge. Plus I will be making a Web Site portion which will showcase armies and conversion guides.
Basically its to have a quick flash intro to the site leading to the main portal. I have a few ideas on this, but then we would need to know what Xander our technical whiz could do.
I can do anything you can think of in your head. Just let me know what you envision.
I have a picture in my mind of where I want CDO to be, and depending on what skills we have access to will determine how good we can make this. The aim being to impress people as they first enter the site.
Sounds like a good plan. I am open to all ideas.
EDIT
Another possible idea is a very simple 'animation' (for want of the correct technical term) on the main banner itself? IMO the banner should be changed anyway at a point in the distant future. Its fine for now though.
That's more difficult. As the MyBB system uses images to be displayed in the top. I would have to hack it someway for a flash banner. Unless we just use an animated Gif, in which case we will have colour loss.
Whew. Good stuff. Don't forget, you are an Admin too.
