CPlus Classifieds is only a 3rd party gateway mobile app for multiple classifieds sites. Given that, we are only able to answer questions related to our App but not the actual marketplace sites.
Our app aggregates multiple providers. Inside the app, you may go to the side menu -> Settings -> Providers(at the bottom) and unselect/select them based on your interest. Please hit the "Contact Us" button below if you still see issues after that.
Long press the email body and find the "Insert Photo or Video" option in the context menu on the second page. See here.
On the main page, you can click on the city to add more cities.
