after Wiki Indaba 2019 we discussed in the telegram group that it would be good to improve the categories for media on commons for Nigeria (which hosted this Indaba). I started by creating several categories - Quality images of Nigeria, Buildings in Nigeria by city, Buildings in Ilorin, Roads in Ilorin and Roads in Ibadan. It would be lovely, if people started helping to fill those categories and create similar ones.
If you are interested in helping, but not sure how to create categories, please suggest categories for creation here in this thread and I (or someone else hopefully) will either create it or walk you through the process of creating it.
If you have questions regarding categories, feel free to ask them either here, or to me privately.
Some general rules for categories on commons can be found here
