Hostname and HTTP port: These are what your external users see. They are used when RAMADDA needs to make an absolute URL back to itself.
Administrator Email and Mail Server: To enable RAMADDA to send email (e.g., password reset messages) enter your mail server.
Server Registry: This is used to support distributed search. Note: More work needs to be done.
Site Access: Controls who can access your server.
Sizes... Control disk usage for anonymous uploads and the cache
File Access: Specify where else (other than the RAMADDA home directory) RAMADDA can access files.
Enable Lucene Indexing and Search: RAMADDA has some initial support for using Lucene (a indexing and search engine) to support full text search. This is experimental.
Controls the display and what is shown. Note: some of these items (e.g, logo image) only show up in certain display templates and others (e.g., enable ratings, google maps key, Facebook comments) are experimental and might not work.
System: Displays system status
Logs: Shows recent access and error log
Maintenance: Clean up the database and dump the databse.
Note - this functionality needs work.
