How to use the Ad Sharing plugin for sharing with authors on main site.

Hi,

I have try setup Ad Sharing plugin but I’m not sure where my users can set their ad code?

I run multisite, but don’t want it to be network activated, so its activated from main site plugin menu.

I see in Settings –> Advertising i can set a ad code, which i think will be the ad shown when it my turn to have ads on the topics, but where can my users/authors put their ad code?

Is it not possible to ad a widget to be shown on pages and topics also or can this only be in site?

Best Regards,
