Here you can get most of the User Contrib scripts from here: http://projects.blender.org/projects/bf-extensions/
In one Addons Bundle.
Simply copy paste the contents of the addons folder inside the zip into the addons folder in your Blender directory.
I will still be maintaining the scripts on bf-extensions, then bundling what is working weekly, so there will be an api ready package of User Contributed scripts for svn builds from graphicall.
The best way to get feedback and discuss the status of scripts is to join #blenderpython on freenode.
There we discuss scripts and help each other out and decide who gets svn rights and stuff like that.
