Rather than have separate draft repositories setup for each GGF, there
should be a common, ongoing draft repositories for authors to submit their
current draft. This respository should be purged periodically (eg. 6 months)
to remove stale documents. The GFD.1 drafting naming conventions should be enforced for submission. GFD.1 calls for this
 repository for drafts that have been submitted to the Editor, but I believe this repository should be open to all 
documents submitted for GGF discussion.

This has the advantage of training the community to use a common location 
to look up current drafts for all groups and have the location be consistent over time (ie. readiliy bookmarkable). 
Furthermore, it has the advantage of encouraging refreshing of drafts between GGF meetings..
