Non-diffusing categories
Please pay attention to whether a category is non-diffusing when you categorize articles. You recently added Radha Kessar to Category:Indian women mathematicians, a non-diffusing subcategory of Category:Indian mathematicians. When you did so, you should not have removed her from Category:Indian mathematicians. Basically we don't want to ghettoize the women and cause people looking at the main category to think that it's populated only for men. That's why we have non-diffusing categories. So Kessar needs to remain in the main category, even though she's also in the subcategory — that's what it means to be non-diffusing. It would have been ok (and I have done so) to move her from the top-level category to the by-century subcategory, but it is not ok to keep her only in the gender-specific subcategory. —David Eppstein (talk) 23:49, 17 May 2018 (UTC)

 * , ref the first and second of thre edits 23:09-23:51, 17 May 2018‎ at Radha Kessar you imho now noticed Category:Indian mathematicians category tree and India women-related categories, hence, you already fixed, Roland zh (talk)
 * Was that supposed to be written in English? Yes, I fixed it. The comment I left on your talk page was less about this specific case and more about how you should not repeat this mistake on other articles. —David Eppstein (talk) 00:06, 18 May 2018 (UTC)
