To all who cannot log in: you can login to the whole page using the "myReactOS" thingie in the upper menu bar. There is only one login spot, since the redesign is meant to integrate all systems without constant logging in. You still won't be able to post in forums and there is no way to log out
1) There are some styles/images missing for forums atm, bug 7263
2) See above.
3) I like using a bunch of tabs
But feel free to file a bug.
4) I'm against linking to current web presentation, the page layout will change and so will the URLs. Let's have most important pages done there first, otherwise there would be still work to do, only later. As you said, the site is not completed, it's just Danny's/Amine's initiative to show us now and have more eyes looking for bugs.
5) The Download button downloads the CMS (content management system) that the page is displayed in, it's a joke (obviously no newbie would get to that page so it doesn't matter), later there will be the download page as is on the current web presentation.
6) I agree. Filed bug 7287
7) I agree. Filed bug 7288
