The other projects are listed under others. I pretty much copied SOLR's layout and then moved Lucene Java XDocs into the site structure, so I think they are at least consistent with the other sub-projects.
Also, not sure about the logos. The other sites have our "original" logo on the left, as the Lucene brand, and then their logo (SOLR, Hadoop) as the larger icon. Lucene Java has always used the green Lucene logo, so I wasn't sure what to do, so I had it up there twice. But I like the feather idea, so I have changed that
On Releases, Steve Rowe suggested that I change the menu link to be "Downloads", which I have done (I also added a info on how to get the source code)
Otis, thanks for the Lucene4C info. I wasn't sure on it's status, so I left it as is. I have now removed it.
Yonik, I agree the website update info should be made generic, but that is beyond my control for coordinating across projects at this point, so I am going to default to copying for now. I would be happy to document/help w/ any top-level coordination to make it easier for any future projects that fall under Lucene (I'm holding my breath for the Pascal version of Lucene ) or to come up w/ a standard template for docs.
As always, the changes can be seen at http://people.apache.org/~gsingers/site/ (you may need to refresh or clear your cache to see the changes)
