I agree 100% that all the Tiki sites should use the same theme (but possibly vary the colors). IMHO, it's very confusing for first time users being bounced around different sites (where they might expect there just to be just one huge website). Pick a colour coding scheme and stick with it e.g. Blue/Grey default portal, Black/White development portal, Green/Blue document portal etc etc.
Users should be able to get to and from all the various sites, and the navigation should be similar across all of them. Obviously they won't be 100% alike as some features are more pertinent than others depending on the portal.
New users might potentially find the whole "tw.o" thing confusing too. "Is the development website address dev.two.o?". However, it is good word play and particularly relevant given that version two will be out soon.
If this is the re-launch of tw.o, might want to remove the reference in the header on info.tw.o to "proposal", but keep the link to this page somewhere on the main page.
Second issue is that getting back to www.tw.o or tw.o from info.tw.o is not very intuitive (for example, to access My Tiki). Having to go to Tiki Community->Community (to me, anyway) suggests the dev site.
I think for new users to Tiki it may not be bad, but for those who are used to the "old' arrangement of the sites, the new names might be confusing and some may find it hard to navigate to where they want to go (unless they've got a bunch of bookmarks).
Otherwise, great effort! Looks great!
