vim-scripts.org used to have one issue tracker for the website and another issue tracker for the scraping robot. Turns out this was needlessly confusing. The issues for the website have been merged into the scraper and now there is a single issue tracker for the entire project.
The issue tracker is also being moved from the vim-scripts account to vim-scraper (the GitHub support request). If the vim-scraper link 404s, then the move hasn't happened yet. If it resolves then the move is complete.
UPDATE: The move is done. Thanks GitHub!
