Hello. My name is JoÃƒÂ£o Alves and I am a participant on the Google Highly Open Participation Contest.
Nouveau is my second theme and it's a pink and green theme compatible with the blog, forum and e-commerce modules.
Please see it in action on the [url=http://demo.silverstripe.com/?theme=nouveau&flush=1]online demo[/url] and [url=http://www.silverstripe.com/assets/Uploads/nouveauv2.tar.gz]download[/url] it if it's of your liking. :)
http://demo.silverstripe.com/general-discussion/ looks a bit rough. A couple things you could try is to use a couple graphics to separate the areas around the forum maybe a background on the search on the right. The currently online heading and the text is a bit big don't you think for such a small feature as that? Its way too big on the default theme but thats a bug :P If you just reduce it down to 1.1em or around that so it doesn't overshadow the forum threads that would be good
A couple other suggestions would be to remove the padding left on the h2's. It looks a bit weird having 25px of space there. Nudging it in is a good idea but perhaps only 2 or 3 px.
The link you indicated looks different because of some caching error on the demo site. For some reason it loads both the "themes/nouveau_forum/css/Forum.css" style sheet and "forum/css/Forum.css", which overrides the first.
I've tried it on my local installation and it looks fine. Please check on a fresh installation of SilverStripe.
What I was saying the currently online text is too large, and it doesn't need to be so large. and on the forumholder you have alot of information at the top and I suggest maybe it would be nice to break it up a bit. Eg put the login form and links in the box with a different background and a border just to give it some structure eg I did this in Firebug quickly to just show what I mean
Forum.css (line 710)
border:2px solid #CCC;
That breaks up the large whiteness up there and gives a bit more structure.
