We've add Admin UI to strip revision on Mercurial remote repositoy (OSDN server side repository) for project.
You can submit strip request on Project Mercurial admin UI. On the admin UI repositiry list, each repository will have Strip button. When it is clicked, strip request submit UI will be open, and you can submit the revision you want to strip.
Please be careful to use it. Stripping is very useful, but cause of truble when working with multiple people.
