Source Code Apache Wave resided within the Apache Incubator's Subversion <http://subversion.tigris.org/> repository. Anyone is free to view and checkout the source code. Only project >>memembers<< may commit directly to the repository, however feel free to submit a patch. If accepted a committer can commit the code on >>you<< behalf. Should be "members" and "your." Every page on the Internet needs a "contact us" button for stuff like this.
