I'm trying to find the gdc-0.18 alpha1 that was supposedly released some time ago.  Is this still available?  I'm trying to figure out the best way that I can help move gdc forward but want to start from the "latest" sources.  I've looked at the D Bugzilla site for some ideas on what I can start on.  I'm not particularly familiar with the internals of gcc so I'm not sure how much I can help in that area but I'm very willing to write documentation or help clean up libraries if someone wants to make a suggestion on where I should start.
