Right now, you can't download it. I want to do a couple of more test installs before I release the download version. Local installs will be the hardest to patch, so I want to make sure I got it right.
However, there are links on the site above to sign up to the central server and to OOTP's Official League Server. There are also on-line help documents there to help you through the process, as well as a message board to post suggestions or problems.
Please don't post here with any problems. Post any problems on the message board on the BOSI site.
I'll let you know as soon as the download version is ready.
