I do hope they get the registry site straightened out.
In the interim, several of us are working hard to improve
http://gimpscripts.com and make it into a complementary alternative to the registry, with perhaps a little better file organization and free from comment spam. Comments are automatically filtered for spam and all others are moderated, unless the commentator has previously approved comments, then their new comments are posted without moderation.
Script authors can submit their scripts via a simple form and the submissions will be moderated for spam, and other QC checks, before they are posted. Script authors can also contact me, or any other member of the staff, if they wish to become gimpscript.com editors and add/update their own content. This might be a better paradigm than is currently used at the registry.
