If you meant for the page to be deleted, blanking is not the right way to do this as blank pages will cause technical problems !
Please use "{{Badname|type good new name here}}" if the category has been moved to a better name, so that the other users are informed about the new name. Please use "{{speedy| type reason here }}" and add it on top of the page you would like to have deleted.
This way it will be placed on a special list that administrators check regularly for deletion.
Without this it might take a long time before it's noticed or it would be forgotten about.
Redirecting / moving / renaming
Categories:
If a category should be renamed please propose a move by putting the {{Move}} template on the category page. The Move-template is used when you want to propose to move contents from the current category to a another one. See Template:Move for more information. If this category has been moved but this one should be kept as a redirect use {{Category redirect}}. {{category redirect| Name of target-category (without the "Category:" prefix }}
Files:
If you recently uploaded a file under a wrong name use the {{Rename}} template. => "{{rename|new filename.jpg| type reason here }}"
If you've already uploaded the correct version of the file, and want to delete this one, use the {{Bad name}} template. => "{{bad name| Name of the correct file.jpg }}"
If you are not the original uploader of this file but found a duplicate, please tag it with {{Duplicate}} => "{{duplicate| Name of the correct file.jpg }}"
In case you aren't sure what to do, it's best to ask for help at the help desk.
