10:24 PM Misc #19679 (Assigned): Migrate Wiki from bugs.ruby-lang.org to ruby/ruby GitHub repository
- I added @jemmai to Triage team and added wiki CRUD grants to Triage team.
If you don't have wiki permission, please ask me again because configuration of Redmine is too complex. -
05:31 PM Misc #19679: Migrate Wiki from bugs.ruby-lang.org to ruby/ruby GitHub repository
- @hsbt I think @jemmai should have Wiki edit permission on Redmine for updating/deleting migrated pages. Can we maybe create a group with "Triage team" permission on Ruby master and add Jemma to it?
