MagicSpark,
A build is as easy as "ant cbuild". Auto-upload's nice but not really essential.
The longer part is just testing it to make sure the build works with the included libs, not that that takes very long either.
You've got the FTP details, so please feel free to create and upload a build

. "ant cbuild" also builds and includes the toolkit and creates the third-party archive. Make sure the third party libs are up to date with the correct versions, and make sure that your toolkit is checked out in a directory that can be reached by ../xith-tk/ from the script. I recommend using a unix environment (linux, osx, cygwin for windows) to do this build.
If you like you can also update the javadoc and source directories.
Cheers,
Will.
