If you are requesting adminship or bureaucratship, and your wiki has a local bureaucrat, submit your request to that user or to the relevant local request page (index).
For urgent requests, such as to combat large-scale vandalism on a small wiki, contact a steward in the #wikimedia-stewards接続IRC channel. In emergencies, type !steward in the channel to get the attention of stewards. Otherwise, you can type @steward for non-urgent help.
Other than requests to remove your own access or emergencies, please only make requests here after gaining the on-wiki approval of your local community.
