In the input box you need to give only the name of the Commons Category, without the full URL or the Category: prefix.
For example, I did test the tool with this category :
https://commons.wikimedia.org/wiki/Category:Seiko_watches (only because it has 40 images which seems good to me for test purposes. I did *not* want to test with the thousands of pictures of the contest category from last year ;), if I type "Category:Seiko watches" the tool throws an exception, if I type "Seiko watches" it worked.
So I do have 40 pictures loaded in the tool, but now I cannot find how to :
- rate the pictures
- add new accounts for jury members
- change the password of my own account.
If someone knows how to do this, please help ;)
