Rael has announced that you will always be able to download the latest version of the Blosxom 3 Alpha at this link. The trouble (?) is older versions will be lost over time. In the interest of keeping a record of changes to the build we will maintain a list of each alpha version, which you can find in this story (use the permalink below to bookmark it).

Alpha One (download)
Alpha Two (download)
Alpha Three (download)
